Importing User's Email Address

So is it not possible to transfer a user's email address over from Facebook into Joomla or JomSocial?

If that is the case, has anyone figured out any sort of workaround to this issue? Getting the user's facebook email address or at least transferring them to a page (after they first login) to enter in their email address would be a very good idea.

I've got too many Joomla components (JomSocial included) that use the user's email address to send private messages or other such things that getting it into my site's database is a huge priority.

Anyone have any suggestions?

As far as I know for JFBCONNECT, at first login, FB user will be directed to a page where they can fill in or change (to be exact) their email data. But still, this is not good enough, as user tend to just click continue without bothering to change their email address.

Probably user can be forced to change their email data with some validation rules in email field otherwise it can not continue to log in. Though, I am not sure this is the best way ...
