Ah, yes. Such was the discussion Alex and I had about the chat room. We had this Flash chat that was more compatable but less customizable. We switched it over to the current system.
It doesn't work for me, either, unless I use a different web browser. What browser are you using?
Try using Mozilla, Firebird, or Camino, those are browsers that I have tried that work: http://www.mozilla.org
Everybody, what browsers are you using, and are you able to access the chat? Tell me, so we can figure out what works and doesn't, and we'll post that info on the chat page.
