On the activity charts, the bars are the number of submissions plotted against the 2nd (right) y-axis. We could really use more Warhammer submissions. Even 1 regular submitter can make a big difference so download today!
A Warhammer branded site is in the works so hopefully we'll be able to move to our own Warhammer area with easier to find Warhammer data soon!
Oh, and currently in order to search the Warhammer data for a character or guild, you currently do a normal search by entering in your query in the box in the upper right of the site, and then you must click the follow up link to view the Warhammer results. Kinda clunky I know, but I wanted to put something up now until I can get a better solution.
