Public vote on a proposal for sub-forums within the Classifieds forum

Would it be a bad idea to integrate a "proper" classifieds section instead of having it in threads etc?

That's Microcosm.

Not a bad idea, just that vBulletin has no good solution for it, would require a substantial amount of hacking and then would be difficult to maintain.

What is being proposed here is basically a stop gap to help us get through the next year or so.
