Title says it all. I don't think this is a high priority issue, only that it's pretty fun to go on a team and soak up comm votes then jump to Mr Xs team and watch him get angry that he loses the vote.
how to change ingame name eighter? (have looked at http://motd.firebit.co.uk/CheatSheet.html because guessing its a plugin command...)
You change your steam friend name. It didn't ring a bell that your Empires ingame name was the same as your steam name?
