Thread permissions

I reckon you're short on bullet point 1 by 20 posts, so bullet point 2 seems an option:
  • New members will not be able to use the section for selling until they are deemed to be active members, this will happen after 30 days and 30 posts.
  • If you can't post because you have not reached the new member threshold, you can send the seller a PM. Sellers can add the PM received information in the thread
