You can sign up to one account with your email address. If you signed up for an account but did not verify your email address, the account will automatically be deleted after 48 hours. You will then be able to register again with that same email address, but will have to choose another unique account name.
Should you still not be able to sign up after 48 hours, please contact our support team for assistance.
If you previously signed up for an account and verified your email address, request a new password to access your account.
