In the latest build of 3.31, the number of reviews in the Reviews column of showmembers.php doesn't appear to match up with each user's actual number of reviews.
For instance, on http://s89196893.onlinehome.us/test/showmembers.php
, it shows the user "test" has 2 Reviews, but if you click on their name, it shows 3 reviews. 3 reviews is the correct number, as I did 3 test reviews.
This also happens on my live build: it shows that I have 10 reviews on the list view when I really only have 1, and it shows another user as having 0 on the list view, when they actually have 9.
