I think it is Peer 2 Peer and not a client server model. Or at least we dont act as a server, but ICQ's servers may. So in that sense it may be a clent server model. But all you have to do is request a chat and keep adding users I believe. I am pretty sure I used to use ICQ for that. Anyway, that is not really important. What is important is that everyone will need the Pro version to do multi person chat.
I havent heard from Johnny yet. I will be floating around on ICQ, anyone wants to chat I will be there.
