We are looking at monetizing our Classifieds area, and I am looking around to see if there is a way we can charge per listing (meaning, we generate a charge each time a thread is created). It would have to be self-administered like subscriptions are, where members pay their fee, and then could post. Even if there were an auction add-on that let us charge a per-listing fee, that would work. Anything like that available here? I only saw one add-on, but my search terms were too vague to find anything else valuable. We already need to purchase the XenCentral Trading System to replace XenTrader--I wish that product had something built into it.
