This has been done on another community I visit that uses vBulletin.
On that site, in the user Control Panel, you can select forums that you don't want to see when you click on "new posts".
If that's possible here, I'd really love it. That way I could read all the thread topics that got posted in the specialty forums without having to also sift through introductions and student posts, etc. The way it is now, if I visit the site once a day, I get 20 pages of results when I click on new posts!
