Yesterday I was testing to see how long it would leave me in there and hold on to text. It seems to be working well. It left me in there for a couple of hours without touching the 'puter.
One feature I really like is that you can send a private message to another user. If you click on the "PM" next to the username in the upper-right, then you can send a message that only that user will see.
Also it works so much better then the old chatroom... keeps the server running much cleaner. I'll be popping in there once in a while today. I have had a few chats with other users but I would really like to get at least 5 or 6 in there to see how it does.
Oh... and I did do a notification thing on all the forum pages that show which users are in there. If you go in there, it will sow on these pages. If you close the chatroom window, 30 seconds later it will erase your username for the queue.
