I clicked Yes, then it asked me to register, so I typed in my info. Then it says check here to agree to the terms and conditions, so I clicked there, and it took me to that page (normally I would have middle-clicked, but I was pretending to be a normal user). So I read the terms and conditions, and when I'm done I want to go back to sign up. So I press back, but my browser pops up saying "Do you want to resend the information?" I press Yes, and all the text I entered is blank.

Possible solution: add target="_blank" to the terms & conditions link.
