To convert an unregistered account from unregistered to registered
- You must hold the browser cookie of the unregistered account (these accounts are cookie-based by definition).1
Click the 'register' link at the top of every page.
After adding credentials, your account will convert from unregistered to registered.
If you have accidentally created a duplicate account -- that is, you now have BOTH registered and unregistered accounts, email the address printed at the bottom of every page with URLs to both accounts and we can merge them.
1 If you do not hold the cookie, use the account recovery page and it will email you a link to reinstantiate the cookie. That's assuming you have provided a valid email address to us originally ... we don't check.
