Need app with multi-user chat support

[erijacob]

Is there any app that will allow for 3-4 people to share a text conference? kind of like a chat room?

EDIT:
also if it would be compatible with BB that would be even better!

No app exists where a chatroom is possible? I find that hard to believe

MSN talk supports group chat.
