(had to type this twice my browser refreshed the page in the middle of me typing :<)finished reviewing you site.
It would be nice if you added an about us page. Include a little information about you and your partners if your willing to, definitely put the business address there again.
You should make it more clear that the coin must be mailed back to be able to redeem it. (not a big deal but on the
exchange page you call it the "coin return form" twice but the name of the pdf is "tokenreturnform")
Its awfully nice of you to return back bitcoins at the highest sell price of the day. You should also include information about which site your getting your price from I assume mtgox?
Current Sell Price per 1 Bitcoin token: $5.32
Current Sell price 1 Bitcoin token in Bitcoin: 1.08 Bitcoin
"sell" price should maybe change to "exchange" price?
the last thing I could think of is to add in the FAQ how to exhange/redeem a coin. make it clear that it must be mailed back to you.
