Chevy,
Threads is one of the few (maybe the only?) bulliten boards that allows a member to belong to multiple groups. Each group can have different privliges on each forum.
For example you could have is set up to where a member could subscribe (have ability to post) to Car Classifeds for $10 for 30 days, and concurrently purchase a subscription to the Motorcyle Classifeds for 1 day or subscribe to all classified forums for say 30 days, or 60 days, or 6 months, etc...
I should have a site up for beta testing in about a week. I will try and let you know. It sells online automotive training through forums controlled by subscriptions.
