okay, here's what to do.
1. Go to the regular chat.
2. Disconnect your internet, pull out the router, turn off the wifi, etc.
3. Wait for the chat to disconnect you (changing your name makes it faster)
4. You'll get a connection error note
5. Turn your router back on, or plug it in or whatever to get your internet back
6. post in the text box on the chat
It only lasts a few seconds though.
