i have created a chatroom which you only need java to use take a look http://www.freewebs.com/sci-chatroom/scichatroom.htm
It seems like a nice place but no one is there. I suggest that you post it in Free Thoughts so that it gets more traffic. I also think that maybe we could encourage other forums that are more intelligent to join. For those that are weary, here is a screenshot. Please Register or Log in to view the hidden image!
