tried to create an account twice and it doesnt let me log in!
That seems very strange.. send us an email and we'll sort it out ASAP!
Why do you need my full name?
That's what I'll call you in case I need to email you (for instance, in the case of you entering a wrong bitcoin address and requesting a payout).
If you're paranoid, enter a fake name. We'll never know.
It also helps to identify users who email support from a different email address than the one they use for their account and forget to tell us their account email address. I can just look them up by name and sort the issue out without the need for an extra email.
