I haven't read any of the replies, so maybe this has already been mentioned... Have you thought about selling premium memberships? For a certain yearly, one time, etc. cost, supporting members would get a banner under their name showing they are supporting members, no ads, maybe a sticker, maybe a special subforum? Maybe a dual Smugmug/advrider membership for a little more than just the Smugmug membership fees. I post on a lot of different forums, and I always buy a supporting membership in the ones I'm really active on. Whichever way you end up going, thanks for setting up and keeping this awesome site going.
