Theofficeexperts board is a poor second when compared to this, but with regards to Word, it seems to be the best out there. Your only other alternative is the Microsoft Usenet boards and there's such volume that you tend to get lost.
I'm equally adept at Word as I've programmed several presentation systems using Word as the base (and tying in Excel, PowerPoint, document management systems, other graphing programs, etc...) so if you post a question and I see it, I'll answer it, but I don't normally peruse anything but the General Excel forum daily.
