I just noticed Circleup.com brings to users an option to log in with a Facebook account. I am wondering if you can also export your Facebook friends into CircleUp.com or into other website which is using that option. If the answer is yes, how it seems that? User log in let say into CircleUp.com or any other third party website using Facebook log in system and than he export into his third party website account his Facebook friends. So after that his friends get message by e-mail or to their Facebook site? Please explain me that. Tnx!
