My community is built up around my classifieds section of my forum. Would really like to see an integrated classifieds within Xenforo. I'm currently using VBClassifieds, which gets the job done but no longer is supported. I'm currently a VBulletin owner, and would REALLY like to leave that scene but I'd need something like this to get me to leave. I think classified and buy/sell in general are terrific traffic builders. My members love the auctions and it's one of the more popular sections of my forum.
