I need as a function:
Log in using facebook, the person will be able to allow access and then will allow: Invite friends to tan to pages, post to your name = ok / cancel.
Those placing OK will be registered in the system. (Facebook question ok or cancel)
All registered in the system, the system selects all friends of the person and invite them to tan for one particular page I choose.
The system just does it when I ask. Should I select: All registered or choose just a few.
Once the person is registered and allow the API, I can ask for all of her friends for her to tan particular page or follow certain profile.
