there should be a log of all bans and kicks, and the when a player joins, it should inform all admins that the player has been kicked in the past, and why.
also it would be nice if there was a way to add data about a player, so I could say i think they *might* be a dconer or just a noob, but they quit before i was sure. the future admins know to watch out for them.
just an idea.
