After you click "Create New Account," you will be sent an email from GVEA which contains your verification code. Enter the verification code from the email to continue creating your account. The subject of the email will be "My Account Verification Code".
If you did not receive the verification code email, check for it in your spam folder. If you still have not received the email, you can request the email be resent or change to a different email address if your current email address is not working.
