Clearing Shoutbox/Forum

Here is the reasoning:

user1 posts in forum 2 posts. user1's post count is now 2. You delete one post. It goes down to one.

The post count goes to the database for the post count. It finds the number of posts with author "user1" (or whatever username). When you delete a post, you delete it from the database, and thus the post count goes down one.

You would have to alter it to, every time a post is posted, it goes up one and doesn't rely on the database.

How would you go about that? I believe Top Forum Posters mod for v6.01.15 does this. You'll have to search that code. But I'm not 100% sure...
