The design elements to the top sections are included with the skin as .psd files.

Yeah, I know that the green around the login/sign up link is only on hover, but the point that I'm making here is that the ZeroHour navi looks "lazy." And I know you've done a lot of work on ZeroHour. That's not what it looks like, tho - maybe some spacing to the navi or some kind of identity for the navi can move the potential new member to register or log in... Otherwise it looks like another link on the site.
