A few years ago, Jake submitted an excellent query that recalculates all user post counts. I think that function is useful to enough admins to make it part of the core admin features instead of running database queries. The most common use scenario is when admins use paid writers to post on their forums (most useful when a forum is just starting out). Posts that don't meet a certain quality threshold are often deleted, but in order for a receive a refund for bad posts from the writing service, the post has to be deleted and user totals recalculated. It would be very helpful if this could be done by pressing a button in Admin CP instead of running queries manually.
