Quote - could it be related to somebody with multiple usernames, all originating from the same IP address, trying to access the site from multiple browser windows?  at least that's something y'all can check in the logs.

I don't think any of us who frequent chat do that. The people I know in there have just one username...that's it. I've been using the same name lo these many years. We've had no problems with someone deliberately trying to screw with chat, if that's what you mean. The only problems we've had so far (pertaining to people and not software) are morons being rude to the other chat room members. And that hasn't been for quite awhile that I'm aware.
