Your choice of web address makes it hard to say to people, due to the confusing use of dot as a word just before an actual dot. You end up saying "Free domain dot dot com" which is just confusing, and a web address should
never be confusing otherwise people will simply never remember it. I think Slashdot is pretty much the only website that can get away with it simply because it was a novel idea, and now the site is well known enough that people know the address.
The blue "Step 3" image on the front page has the word DOMAINS in a serif font, compared to the sans-serif font used on the other buttons. It shows you've taken a template and edited it, but couldn't find the original font

Either get hold of the original font to make it match, or change all the buttons to a new font.
You also don't make it clear exactly what is being offered. Your web address mentions only domains, yet you have put the logos for PayPal, Rapidshare and Megaupload all over the site. Do you have permission to use those logos? And make it more specific on the main page exactly what is being offered, as your headline mentions only domain names. Also, you need to be more specific with the domains - who actually owns them once you get one? How long does registration last? Can you renew them? Are they just TLDs or are ccTLDs included too? If so, which ones?
