Guess I'll start it off ID.
Front page, Top Skins, if you click on All Time, you get the listing for Yesterday's skins and vice-versa.
Front page, Top Skinners, clicking on any of the choices, Yesterday, Last 30 days or All Time does nothing at all.
On the authors skins list page (like where you check for new comments, can delete, etc.), on the drop down at top left next to the All button, selecting Most Popular or Recently featured does nothing, and pressing the All button does nothing either (I assume that's to show all skins).
Oh, and this is with the latest Firefox browser and IE8.
