Also once you've registered as Candy said the confirmation email may take a little while to come in but DONT forget about it or take too long to go back to it. You have to actually click on the link in the email to validate your account and it's only open for 48 hrs, if you dont click the link and it expires you'll have to start all over :/

I figure everyone will click their email but just a heads up in case :)
