Thanks, Rob. I voted for sub-forum, but I don't think the support forum should be hidden away. It should be very easily found. My own forum,
The Floor Pro Community has a Website and Forum Support forum in the Administration & Support category. I do the news and announcements from there and there is also a test forum for members only (and hidden from search engines) for members to practice posting images or testing their signatures, etc. What you can't see there is also a staff forum so that me and my moderators, guides, etc. can talk about members behind their backs and devise ways to make their lives miserable.

Well, okay, we don't do exactly that, but we do discuss contest organization, habitually errant members and how we can work together to promote activity and community on the forums. I also have the all-important staff contact list and the job description posts stickied for the staff to have easy access to.
Just some ideas I'm tossin' out there.
Jim
