How do we add a custom registration page before the user is created in the database?

After the user has authenticated with facebook, could we display a page to ask for further user profile detail before the user is created?

I'm also interested in this, as we have a mandatory email address on our profile, but occasionally facebook does not provide the email. Currently this causes an unrecoverable error

Of course you can show a page to ask user email after authentication through FB. But it's unrelated to the plugin, right?

It just requires us to make email an optional field on profile, which is not ideal as we basically use email address as the account identifier. Not impossible granted. I'd be equally happy if we could send an error message back to the user if we can't populate a valid profile - but currently this doesn't seem possible?
