Registered users log in with access of Members
After 20 posts promotion kicks in and kicks them to another group called Members with over 20 posts.
Remove them from the Members group and place them in the Members with over 20 posts group.
I use rank images, and have found that by default it will show for both groups. I use
[RT] User Rank Images, but before that had CSS code set up that I also used.
Any suggestions on how to implement are welcome.
