I think people need to learn to shut up and enjoy the game. People have such a habit of whining that it gets very irritating. Even when you disable the chat box, the admin makes some stupid call and kicks you from the game.
If you want to run an efficient game server:
I have found in more servers than one that admins often have flawed judgement and a terrible relationship with their fellow admins, and this leads to server inefficiency. In an efficient game server, all admins have to know the server security policy by heart and have to follow that policy. Constant communication between admins is a must, and all admins should know where to report security incidents. It's a good idea to have some sort of central incident reporting forum; I usually pull this off by making a private section of my forum devoted to the storage of incident reports. Also, it should be made absolutely crystal clear to the player where and/or who to file a complaint with in the event of a security error; this minimizes the amount of players coming to the MTA forum to whine about a problem experienced on a particular server. Also, admins should be given access depending on their character; more responsible admins can have greater access while unpredictable admins can have lower access.
I've been adminning game servers for six years; I know damn well what I'm talking about.
