To Bish's comment: As fury said, we don't use the board default registered user settings for our registered users. fury and sammy made a bigger and better "registered user".
So, anyway, the Top Poster statistic compiler thing was doing what it was supposed to, and drawing from the board default registered user list which was comprised of nobody.
Now it's been told to ALSO look at the bigger and better registered user list.
To answer Spike: When a body registers at a board, they are placed immediately into a usergroup. These are the basic registered users. Then there are the mods/admins usergroups, and the 'doesn't have 30 posts yet' usergroups. The admins/owners can create more groups as they see fit, to limit capabilities, to add capabilities, or to allow or disallow viewing of forums. Here, this would be seen in action in the "Contributor" usergroup, and the "Window Licker" usergroups, among others. We could always make other usergroups, and invisible forums for those who like baseball, or for whatever else we wanted. But the bottom line is, everyone right from the beginning of posting on every board has a usergroup which outlines what they're able to post, see, and do on the board.
Clear as mud?
