On the Front Page menus, right hand pulldown menu, just below preferences is an option marked statistics. This takes you to wacsstats, the statistics application. The screen shot above gives you a general idea of what it can do - it'll provide top 25 rankings for total number of images, total number of sets, and total number of videos for each model. It also includes, updated nightly, the Yes and No values for which types of set this model does.
Additionally, there's the Queens Of menu (shown pulled down in the screenshot) which allows you to see who has the most toy sets, lesbian sets, etc. The third pull down menu gives you the download statistics which shows you where the known sets come from, how many of them you already have, how many are pending unpacking, etc. Quite useful for keeping track of download progress, etc.
