Hmm...I think a selling section would be nice, but like you said, Jennifer, it could be a liability issue. You know what you could do is make a requirement for people to members for a certain amount of time and be ACTIVE on the board within that time frame. Also...you could
hide the selling section. I used to be on a board where if I didn't log in, I couldn't tell that there was a selling/trading section; it just looked like a fansite to me (it was a site for collecting gemstones...yeah, I had interesting hobbies

). In that way, the moderator could weed out those who just wanted to sell versus those who liked the board.
