There seem to be a major error with user identity on their website. Logging on to the wallet for the second time (after registration) seem to lead to someone else's wallet. I donated the bitcoin to the address listed right after the registration, and after the relogin I have another bitcoin address in the "wallet" with zero balance. Also entering the bitcoin address I transfered the bitcoin to claims to be zero in their checker. I don't know how they're going to fix this mess, I hope I did not lose my bitcoins for good.
