A form with both Register and Sign Up buttons

So do I want to “Register”, or “Sign Up”?  I think I want to Register, and having the check box to accept the terms and conditions is something you’d typically see when initially registering, but it would appear I need a password, which implies I need to already have an account.  Hmm.  I think someone needs to look at this, I bet it’s causing them to lose registrants hand over fist.
