I need an example of a web app which allows someone to log in to their Facebook account from my website, and then send a message or invitation to join my website to some of their friends.
I assume this involves Facebook connect, but I'm not sure. I want to make it so that people can invite their existing Facebook friends to join my website. If it matters, I'm using PHP if that's necessary.
This looks like it's along the right track, but I don't have the knowledge/time to really investigate it:
