>>3Nope, not released yet. Also little time difference between x4xy4 and me (me goes to bed when he comes online) as well as personal stuff made a slow start for the teamwork on the new collaboration product. But well, I am at least working on it at the moment ;)
I think both - a forum like thing and a chat - are important. Chats are good for chit chat, but you won't be able to talk about a topic for a longer time. A forum is good for discussing a toppic over a longer period, but imho are a pain in the *ss when it comes to regular chatter.
