I´m using teamspeak, too!
Everybody, just download this little tool. Then we have to create a MTA server/channel together, and we all would be able to talk.
Different gangs can connect to different sub-channels with different passworts. They could be given the teammenbers before joining.
That would be a very helpless and funny thing! (especially for english people, hearing my very, very bad english "in action")
