On another note, mChat has been working fairly well for me for about a year now, but recently it is no longer refreshing. It makes a beep noise and displays an "Error Forbidden" at every 30 second refresh interval, and then displays "Update is off" at the bottom: http://i.imgur.com/2no8EEg.png
I didn't have this issue with versions before v2.0.0, but they are no longer on your Releases page so I can't test them. I'm also reasonably sure I didn't have the issue with v2.0.0 RC-5, so I might try wiping mChat and reinstalling that to see if I can duplicate the issue.

This might have something to do with my web host, too. Perhaps they sent me the warning I posted above and then did something to limit the script at the same time. I'll check with them as well.
EDIT: Nevermind. This was my web host editing my htaccess file without my knowledge. Having a script running more than once every 30 seconds is against their rules (very basic hosting package), but it would've been nice for them to inform me of the edit. Anyway, thanks for this great extension.
