OK, I've figured out how to add post-based forum permissions (don't tell anyone I have an IT-related degree!
). There are now two member groups:
New Member - Anyone with
less than ten (10) posts
Approved Member - Anyone with
ten (10) or more posts.
To post a new topic in the Classifieds (For Sale/Wanted) forum you must be an
Approved Member. To become an Approved Member, you must have at least ten (10) posts, excluding posts in the Moderation Forum. This will happen automatically when you pass that threshold.
Please do not circumnavigate this restriction by posting your adverts as replies to other poster's topics.
At present there are no restrictions in allowing New Members to post replies to topics (and therefore 'buy' goods) in the Classifieds. We could in the future introduce an intermediate group (for those with between 5 and 9 posts for example) that can buy in the Classifieds but not sell. I'm willing to reconsider this should there be demand to do so.
