Here is a plugin that "should be really great". It auto-detects campers, announces it, warns them (which can be turned off), and (optionally) slaps them. Fully customizable in the file, and customizable at run time through console commands:

admin_campercheck <"1" | "0">
Enables/disables checking for campers.

admin_camperslap <"1" | "0">
Enables/disables slapping campers.

admin_campert <value>
Sets the tolerance in units of how far they have to go before not being considered a camper.

admin_campertime <value>
Sets how often this plugin checks for campers in seconds. Default is 10.

admin_camperwarn <value>
Sets the amount of warnings campers get before being kicked, set to -1 to disable warnings.

admin_vote_camper
Starts a vote for whether to have camper checking on or off.

admin_camperteam <Team>
Chooses which team to check (0=all) (for cstrike: 1 is T, 2 is CT)

Saying "camper check" or "camper-check" will output the status of camper-checking. Saying "vote_camper" will start a vote for camper-checking.

Note: Still crashes on servers with bots. Do not try to use bots, hlds will just crash about 20 seconds after the game starts.

Shady Milkman wanted me to tell you to enjoy it. He sure as hell thinks it's a great plugin, and so do I.

This is now v1.9a

This plugin let's you declare two clan tags, check that everyone has them, and kick anyone that doesn't. Then it puts a password on the server, and restarts the round in 10 secs and sets all match server settings. It can then start a timer that displays the timeleft every minute or with the admin_matchtime command(also through the use of the say commands). The timer can be turned off with the admin_matchtimer on/off command. Then the server settings can be restored to the normal game paly settings and the server name restored to normal with admin_endmatch command. Scores can also be made to display each round.

Added "ZeusMode" (godmode and noclip combined)
Winners of ZeusMode, GodMode, and Noclip will now glow too
Replaced Slay with human time-bomb -- need
In this version, timebomb can kill bystanders
Replaced Slap with slap disease -- possibly fatal
Enhanced Glow by having it potentially affect health
To Stuck I added a slap at the beginning -- looks funnier
Dead players cant gamble.

Player can become a timebomb by saying "kamikazi" in chat. Admin can disable the kamikaze function with admin_timebombs 0 and turn it back on again with admin_timebombs 1. Admin can make any live player without immunity into a timebomb with admin_timebomb .

Commands:
say: kamikaze
admin_timebombs 0|1
admin_timebomb <target>
admin_vote_timebomb <target>

This plugin attempts to provide all-round improvements to the way your server changes map. There are two primary functions:

1. It allows you to set a number of "victory" conditions under which the map changes, based on player and team scores as well as time.
2. It provides a fair means of voting for the next map that is accessible to all players, not just those that are familiar with the plugin.

The Name Management Plugin regulates the names of players that connect to your server. This can be used for a number of purposes:

• To prevent players using the default name for your game mod such as 'Player' or 'Private', which can lead to multiple players in the game with similar names - Player, (1) Player, (2) Player etc. causing confusion, and to Player sitting at the top of your server stats.
• To prevent players using very short names, such as "." which means you don't notice their name appear on the screen when you aim at the camping gits.
• To prevent players attempting to exploit Half-life/ Counter-strike/ Admin Mod script loop holes (many of which are fixed anyway). Many admin commands allow you to use either a player id, wonid or name to identify a player. Some players give themselves a numeric name which may match another players id or wonid, hence causing you to issue the commands on the wrong player.
• To make player names easier to read and/ or type.
• To identify players who are ghosting - i.e. can see each others screen/chat. The plugin can modify their name with a 'LAN Tag' to indicate who is ghosting, announce warnings to the other players, and automatically switch on/off forced chase camera mode.
• To prevent players from changing their name whilst connected. (personally, I wouldn't recommend this)
• If Logd is present on the server, the plugin will not alter a players name until after they have chosen a team, so that they get a change to see the information messages explaining why it has happened.

This plugin identifies the best player on each team by having them glow in the team colour. This gives the player the kudos of being seen to be the best, but also makes them a target for the opposition.

For counter-strike servers there are two additional modes available - one where the glowing players only change at the end of each round, and one where players only glow briefly at the start of each round.

The Natural Selection End of Round Plugin corrects a bug in the Natural Selection mod. Currently when a round ends, every player is moved to the ready room. If there are a large number of players on the server this can often crash the server.

This plugin provides a temporary workaround for this problem by moving the players back to the ready room in groups of 8 rather than moving all players at the same item.

The script plugin allows the server administrator to create a script of console commands and Admin Mod commands that will be run whilst a game is in progress.

The script can contain wait commands that pause for a specific time limit or a specific number of rounds. e.g.

wait 10 minutes
sv_gravity 200
admin_command admin_csay blue "Low gravity enabled for 2 rounds"
wait 2 rounds
sv_gravity 800
wait 10 minutes
sv_airaccelerate -15
admin_command admin_csay blue "Matrix jumping enabled for 2 rounds"
wait 2 rounds
sv_airaccelerate 15

This plugin updates the admin_t and admin_ct commands so that if they are used on a player that is alive, the team change does not actually occur until the end of the round. This prevents the administrator from killing a player when attempting to change their team. The usage is no different to the standard plugin_cs versions, and there are no configuration options.

The Whois plugin keeps a record of all players that have played on your server. It can provide details on the different names they have played under, the frequency at which they play and their relative performance when there is and isn't an administrator present. It can also detect players connecting from the same IP address but with different WONIDs so you can tell when a banned player returns with a new WONID, and it can mediate which players are required to use Cheating-Death.

Main features:

• In-game reporting
• Browse whois database from the web
• Integration with HLGuard
• Tracks your admins' suspicions on individual players
• Cross-references IP addresses and Names to detect banned players rejoining
• Reports on players rejoining after being temp banned or kicked, or leaving then rejoining with a different name
• Spots players connecting from the same IP address or subnet
• Logs repeated or suspicious team kills
• Cheating-Death mediation - the plugin will determine when a player needs to use Cheating-Death

So, some Brat comes on your server and tks you. You are out for blood, you want to nail him to a wall by his pre-pubescent testicles, your 20 for 1 average is now ruined and you are positively seething. This provides a method for revenge. THe options are "Forgive", "Nothing now", "Slap", "Slay", "Kick" "Temp Ban" and "Perm Ban". Now I wholly understand that you wont want people to immediatly ban the guy for one TK, so this allows you to set levels of TKing. At each level a new option appears on the list for you to choose from.

Where this plugin differs from most is that it holds individual TK records. You can only forgive a person if they have TK'd you, so you cant forgive for someone else's TKs. THe level at which they are punnished is still counted on how many TK's they have comitted globally.

Example:
Assume Bob killed Bill. Bill now has the option to "Forgive", "Nothing Now" or "Slap". If Bill chooses "Forgive", the TK is removed from Bob and his Global TK's decrease. Suppose Bill chooses "Nothing Now" and Bob kills Bill a few more times, Bill will see the "Slay" option appear on his menu. Also, if Bob goes off to TK Kate and Fred a few times, Bill can call his TK menu through "admin_tkmenu" and see who has TK'd him. As Bob will be on the list, he can punnish Bob to the limit of the Level at which Bob is globally, even though Bob only TK'd him once.

To stop repeated punnishments there is the option to forgive a TK when someone selects a punnishment, but this can be disabled so people can just increment their TKs ad infinitum (or until they get kicked).

I recommend you read the documentation and try it out to see the full potential.

*NEW* Additions and bug fixes by Spin-Doc

Ever being annoyed by people begin defusing too often? You can push your Psychostats skill this way very easy, if the award is given (default).
This plugin will slap him after 4 tries and slays him after 6.
This is a CS-only plugin. Hmm, I think this is obvious. ;-)

I was sick and tired of spawn killers in maps like awp_map, the fy_ series of maps, de_box, etc. Those maps were poorly designed so that some spawn points allow you to see your enemy right when you spawn. If you still have that sniper rifle from last round (or just get those lucky head shots), you can sit there during the freeze/buy time aiming directly at your opponents head and just keep pressing the fire button until the freeze time is over and everyone starts moving. Well, except for your enemy of course. You sniped him the exact instant anyone was allowed to fire preventing him from being able to put up any defense even the simple act of moving.

This AdminMod/LogD plugin will punish any player who kills another within the set number of seconds since the round starts. The punishment is usually getting killed for that round but is configurable. Right now the default time is set on two seconds, but you can always change that.

Added commands:
admin_ft_sk_spawn_time - seconds from round start when a kill is a 'spawn kill'
admin_ft_sk_announce_time - announce more details about why someone was punished
admin_ft_sk_type - How the spawn killer should be punished

This plugin will randomize the teams in a CS game (although the source can easily be edited to allow for randomization in different mods). It will also balance the teams when randomizing so that you don't get thrown off balance when randomizing.

A lot of events of the game Counter-Strike (since v1.5) are detected by this plugin and can be announced with a message and sound.
The messages and sounds are stored in vault.ini and can be edited.
If you use the "plugin_sdal_allowsounds", every client would have the abillity to enable/disable the sounds, if he wants/does not want to hear them.
If you use the "non-colored" version of this plugin, the messages would be also enabled/disabled for him.

For disabling the sounds/messages, the players have to enter ".stop" in chat.

This plugin will set the c4 timer (Counter-Strike only) to a random number from 15 to 90 seconds. When a terrorist plants the bomb, he announces to his team how much time is left (in seconds) before the bomb explodes. Admins will be able to enable/disable this plugin with the command "admin_randomtimer".

Makes any connecting users during a full server get redirected to the IP specified.
This plugin will not redirect those with ACCESS_IMMUNITY.
I used this with NO reserved slots on server. This plugin compares current PlayerCount to Server Maxplayers. If they are equal and the player does not have ACCESS_IMMUNITY, the player is routed to the specified server IP and port upon the server reporting "Player entered the game". This is generally right when the player will start to see the map come on screen, right before the MOTD or the map briefing.

VIP_Assassinated = All CTs die.
VIP_Not_Escaped = All CTs die.
VIP_Escaped = All Ts die.

This plugin makes players without C-D glow the colour of their team at the start of each round (Yea, you figured, cstrike only). Also gives them a message when making them glow. Requires StatsMe OR LogD.

This plugin is only useful on larger servers. If there are more than 9 players connected, and one of the teams only has one player left, warning messages will be given by the server to hurry up. After a warning or maybe a few warnings depending of if there are other votes going on, a vote will be put up to either have the server kill the lone player, kill the opposite team (both options ending the round of course), or just leave them alone and let them finish.

Announces killstreaks: multi kill, ultra kill, killing spree, monster kill and godlike.

Modifications:
more wav files
there is no maximum killstreak (keeps repeating "godlike")
clearer messages with for example "(15 kills)" added.

Protects your server from lame TKers.

Short description:
- Detect and response to team kills (TK) and team hurts (TH).
- Let the victim decide what to do with his TKer: kill, slap or forgive.
- Slay the TKer when he has reached the TK limit, and ban him (for a few minutes) when he has exceeded the limit.
- By default, 100hp team damage triggers 1 extra TK warning.

The map vote plugin lets users vote for the map they want to play. It includes the ability for an admin to manage maps votes, including denying a map for a particular vote, and quarantining maps so users cannot vote for recently played maps.

If you have ever played on a friendly-fire enabled server, you know how frustrating it is to get shot or killed at the beginning of a round. It seems that all n00bs joining the server automatically empty their first clip into someone to see if FF is on, to be annoying, or even for no discernable reason.

The spawndamage plugin will automatically slay any user who teamdamages within a few seconds (customizable) of the round. After a few rounds of being slain quickly, efficiently, and without fuss, they will either refrain from shooting teammates, or leave.
