That's a problem I've been working on. I've been waiting on the new forum software before adding it.
The forum upgrade has been delayed again (out of my hands). However, I'm expecting that the second to last release of the software will occur in the next couple of days. Originally, I had said that I'd be upgrading the boards around the end of November. It now appears that it will be early January.
Anyway, back to the point, I will attempt to take care of the chat question when I upgrade the board. I can't guarantee that it will work as I've intended, so I may have to work on it some more after the new board. Basically, no promises (as far as when it will happen), but it is something I'd very much like to improve.
