I'm trying to create an account, but I got a "Not a valid email" message. What do I do?

The "not a valid email address" error appears when you use an email address that contains characters the form does not recognize.  Known character problems: -@ (hyphen in front of the @ sign) . If you experience this problem, please use another email address to create your account.  Your institutional email address should be used if one has been provided for you.
