To make it easier for you to access your model, you can log in on goSupermodel by using your Facebook account.
The reason for not seeing your model could be one of these:
You're probably logged in on someone else's Facebook account. Open Facebook and log in as you instead.
It's also possible that someone else has registered their model on your email account. If this is the case, click "Not your model?" in the log in pop-up. That model will no longer appear on your list.
