fanktv - We have a membership site for people in the horror film industry with a forum and classifieds. I set it up so wishlist takes care of registration for everything and we give all our members free ads. We are thinking about charging for featured ads, but we just launched and want to populate the site a bit first. The url if you'd like to check it out, is
http://horrorjobs.com
One issue I found was that if I set the default member level to contributor, it didn't list them as the poster of the ad and their responses came to me instead of them. Also, they couldn't edit their ads because
WP didn't think they'd written them. When I changed the default to author, that was all fixed.
(With changing it to author, though, there is a WordPress link at the bottom of a member's own listings to edit the ad, but it tries to log into the back-end rather than their dashboard. I had to hack that to make it work, and I'm not yet completely satisfied with my fix. - here's the thread talking about that:
