Custom Mini-Profile Backgrounds allows each member of your forum to set a custom background image for their mini-profile. Staff, with the ability to edit profiles, also have the ability to modify individual's mini-profile backgrounds.
Clicking the personal tab in edit profile will not correctly load the field to set backgrounds.
