Agree with bland, but consider Google. Anyway, it is not clear what the "Web Master" link is all about, some explanation there would be nice. To me the "How it works" explanation needed some work. I didn't like the distribution of links. The "About us" and the "Projects" links should probably be at the top. Maybe a little more explanation on the first page what the site is about.

I am not sure what the advantage of this site would be from what I saw. My first impression was not good. On your response to registration what does "Click here to back" mean? Also on the registration "Zip" is a US thing, if you want international registrations change this to "Postal Code". On the keywords page, no explanation of what "RAC", "GAC" etc.. are. Clicking on keywords goes to 404 page.
