We have tried out the Chat box yesterday, and it seems like a good idea but not as a permanent feature.
When we have an event or a special live debate about something, we will put it up with a notice on the Chit Chat forum as to when it will be held, then those interested can log onto the Chat box.
We have experienced some lag while using it, but that could have been because the server was ...well...being serviced... These are my thoughts on it in the mean time, but it's not written in stone... So let me hear what you think about it.
love and rainbows
