hey dejected
I know this is kind of an old post, but if your still looking for suggestions, you could take a look at
http://forums.studentdoctor.net/ and
http://www.mediamonkey.com/forum/viewtopic.php?t=8709 for some ideas how other sites do it (... sorry, they're not the most clever of examples, but you'll get the idea.)
in the first site, they've got a crap load of main forums, but most people use only one, so they try and keep it accessible by having various subforums. (scroll down the page, you'll get the jist). On top of that, if you click into one (try the USMLE one), they've got a whole bunch of stickies for THE main topics everyone is looking for. You could maybe do a couple of stickies like "Dan - the Man," and "The Music" "The Movie" .... so, everyone if everyone is going into fan forum, it's still navagable.
The other site is much more boring, but it's just a thread someone started and the host was able to politely redirect the guy to a thread already going.
hope that helps.
... btw, if you see Dan anytime soon, give him a hug for me!
