I’ve created a small whitelist plugin, that will allow only the players you want to join your server.
Installation: Just copy it into your plugins directory on the server and let it create the config files for you.
Configuration: In whitelist.properties you can set the kick message and the names of the players, who are allowed to modify the whitelist. In whitelist.txt you can add all the players you want to be able to play on the server. One name per line.
Commands: The following commands are available:
/whitelist help
/whitelist reload (reloads the whitelist and it's settings)
/whitelist add [playername] (adds a player to the whitelist)
/whitelist remove [playername] (removes a player from the whitelist)
Note: You will need the latest version of bukkit for this to work.
