A command for the server to mute people client side, because sometimes people are having spammish conversation on my servre and I don't reeally want to stop it, while I don't want to listen to it. Also maybe let the mute option still record the chat in the chatlog, just not appear in-game.

And I'l join Hunters string changing requests, how about a /rkick and /rban where r stands for reason, and when you kick/ban the banned/kicked guy will have a "You were kicked because " screen. Example; "You were kicked because you are a troll". You can even make it better and add the username of the guy who kicked/banned you.
