The following is to clear things up for people trying to add their mod and or site to the topsites system and are finding it confusing!!
To list a mod you must add the mod than go into your Control Panel than you select manage under Modifications. Once you have done this you select the mod you added. Again selecting manage select Get HTML and choose either the moddb or the new html icon recently added.
To list a site all you need to do is go into your Control Panel than you select Top sites at the bottom!
