If you use Facebook to login but don't have a valid email address registered against your account, then please add one here.

Please do this with some urgency, as the future of Facebook login support here is very uncertain.

From an App (Android and iPhone/iPad), select "preferences" from the main menu, then the "service" tab. You can then update your email email address if necessary.

The recent issue with Facebook disabling RHP login has now been resolved, but the original message still stands - if you do not already have a valid email address added to your account, please add one, so you can continue to log in should this happen again.
