All accounts on our site must utilize a completely unique email address. If you are receiving this error message when trying to register, it means that there is already an account on the system registered with the email that you are trying to provide in the registration form. Please take a look at the email address you have provided and ensure that there are no typos in the spelling. If everything is correct, please take a moment to check your corresponding email account for that address. Your registration may have gone through previously, or you may have an older account on the system that was upgraded to the current portal. You would have received a registration and/or Welcome email from the site when that registration went through. If you do have that registration email, then you already have an account on the site and can go straight to the Login without needing to register again. If you have forgotten the password to login with this account, you can use the Forgotten Password process to retrieve or update your password if needed.
