I am integrating a social game into my website in which people confess what they think about
their friends unknowingly. And send those confessions as notifications to their friends.
I wan't to have access to their friends through facebook login service, which i have not used before.
Can i accomplish these things with fb login?
1)Sending the notifications to the player's freinds, whatever he enters about them respectively.
2)Inviting them to play my game.
Should i have to register an app for this purpose??
