You can only sign up again if you use a different email address. Once you sign up with an email address, it doesn't allow you to sign up with that email address again.

You also can't sign up using a username that has already been claimed. For example, if you signed up the first time and used Stu, you can't sign up again with Stu even if you use a different email address.
