The @unknown.com email addresses are only created when there's no email address available for the user. That can happen in 2 ways:
1) You are using the "Facebook User Only" setting (where the user is automatically created) and are not requiring the email permission (in the Permissions tab in JFBConnect configuration) from the user. In this case, we simply make up an email address.
2) There's a problem communicating with Facebook and we can't get their email address.
If it looks to be #2 above, can you answer the following:
* When the user goes to the registration page if it shows "Welcome Bob", or whatever their first name is? If it just shows "Welcome", that means we might not be communicating well with Facebook at all (aren't getting their first name either).
* For the users that are created, can you let me know if the user's name is pulled into Joomla, and if not, what's that being filled in with?
Thanks,
Alex
