What kind of problems, specifically?

Chat is like our web server -- it's either on or off. The past two times it's been off is because our server rebooted and it wasn't in the startup routine for the server (this problem should be fixed now).

If it's a problem with connecting to chat, and they've tried different web browsers, they should PM me privately so I can troubleshoot some of their ISP info.

Thanks,
