I'm really confused. Most of what should be links according to context don't do anything. I can't login or register, as your input fields don't seem to be part of a form. The input fields persist on your Golf Real Estate and Golf Specials pages, with text overlapping from those pages.

Your sign up button seems to point to the right, where there's no place to sign up.

Ditto Dave's comment about the home button in Firefox 2.0 under Windows; the effect seems to be the same for any selected tab on that row.
