Hey guys, it looks like I've encountered a problem where some customers sign up, then get to paypal page, but then closed it because they might have second thoughts, BUT .. some do go back to the paypal pay and decide to pay. The problem is that the email and username they used their first time is already in use. Is there a way to go around this? Maybe allow duplicate email and usernames until customer goes through with paypal and their account is verified and no one else can use their email or username? Thanks.
