See Members specific content counts in list, not 1 at a time

[fourday]

I want to offer a free subscription to those who have posted X number of articles in the database or posts.

Is there a way I can pull a list of members with a breakdown of content count next to their names?  (articles, posts, comments, etc)?    Currently I can only find this data IF I go member by member, and click on content.    

For example, I can't see how many database records someone has done.   When i go to the database in ACP, and choose database / "Manage Records", there is no sortable field for "members".  (only title, date and category).

Is anyone interested in developing a utility tool for this?

Thanks.
