I was just messing around with the members list for a bit when I noticed something interesting. Sort the users by posts, then go to the last page. Notice anyone missing? (Currently this is page 48, as more people join, this will keep moving. To see the people with the most posts, you need to modify the URL from
memberlist.php?sk=d&sd=a&mode=&start=1175
to
memberlist.php?sk=d&sd=a&mode=&start=1200
this takes you to page 49 of 48 which has most of the regular posters here on it.
You can also do this with sorting by name or join date, etc.
Since it's currently report 1190 users, having 1175 being the start point for the last page (which contains 25 people) makes sense, so I'm guessing that there's some miscounting going on with users.
