Isit possible to allow users from certain domains only

We don't have the option built-in to JFBConnect to limit registrations based on a specific domain for the email address. Generally, what we've seen when people ask this question, is that most users don't use their work email on their social network accounts and so therefore, wouldn't be able to register if we added such an option.

What we recommend is simply setting Joomla to require admin activation (and optionally user email activation) and having JFBConnect configured to *not* skip Joomla activation. That way, you, as the admin, will get a notification when a user registers and can choose to activate them if they should be allowed access.

I hope that helps explain, but if you need more help or have suggestions on a a feature you'd like to see, please let us know.

Thanks,
Alex
