A few forums I’ve joined have areas to trade relevant goods with other community members, and I think it’s nice to be able to do that. It seems to go pretty smoothly on the whole, and I’m not aware of the forum owners having any major problems. (The rules have to say that the forum owners aren’t responsible in the end, if somebody does get scammed.) Some places have a participation requirement.
Any thoughts? At the old forum, the answer was no, but it’s a good time to ask again
