I'm looking for an add-on that will promote/demote users to/from an additional usergroup based on X number of posts in the last X amount of time. For example, they must have 10 posts in the last 7 days to keep their promotion.

On one of my sites (digital scrapbooking) we offer some zip downloads and currently, I have a promotion set up for users with 10 posts, when members reach 10 posts, they get put into an additional group that is allowed access to the Download area (ecDownloads). However, once they get to that point, many stop posting. So, I would like the system to automatically demote them from the additional group if they don't KEEP posting. Sort of like a rolling promotion, not JUST ten posts, but ten recent posts to stay in the group.

I have a very small budget, but I'm sure I could throw a bit of $$ someone's way after the first of any month.

Running 3.5.3 btw.

THANKS!
