Yes, I was test driving the chat for the first time & found the 2 user boxes.. one on top gave me an error that the user name was already in use. So when I poped down to the bottom box, it allowed me access.
One other thing if noticed is that if I go to the chat room; then leave and the click on the ordinary forum area it sometimes loads the chatroon instead of the forum. Not sure why but its does it occassionally.
