A basic tenant that some of the newer exchangers are missing: Show your btc price at the top of your site. I have no idea what "No fees" means to you. Not showing your price is just dishonest and a great way to waste the customer's time.

Assuming you literally mean you buy/sell at the last price of an exchange like bitstamp, then good luck with the whole no fees scheme. By that I mean good luck keeping your account and safeguarding from MiMs while simultaneously not charging a dime. I hope you are just a really successful miner or this business plan does not seem to add up.
