can i link a membership site to a FB group, and when you're in the FB group, you're a memb

Hi guys, we're doing this backwards...

we have a fb group, that we want to link up to a website.

we're trying to have only members of the fb group get access to the membership area. is that possible to have the fb group membership and the website membership auto-sync?

looking forward to hearing back from you.

thanks

Symi.
