I see similar add-ons, but not what I'm looking for exactly. I need to split the existing permission "Post Replies" into two "sub-permissions": Can post replies to own thread Can post replies to other's threads The purpose behind this: We require a premium upgrade to post NEW THREADS (ads) in our classifieds forum. ANY member can post replies. However, after a user's premium upgrade expires, they should no longer be able to post in their own threads (they shouldn't be able to bump their own ads). However they SHOULD still be able to post replies to OTHER's threads as a regular member. I believe the above permissions should be able to accomplish this... Let me know if you're interested!
