Im looking for the same but i dont think i have much time to put all new posts in moderation queue.
There are users who add like 30 advertising posts. So i would like to limit post amount to 5 daily untill they are members for like 5 days, if oyu dont have better idea?
Is there any mod for this purpose?
/EDIT: SOLUTION FOUND: (2 mods)
