On my website, I basically want the user to be able to invite their friends to facebook. You have a friend invitation button - when a user clicks on it - the FAcebook widget opens - which will ask for the username / password for users, and as soon as he logs in - he will show him a list of his friends - he can choose friends - and they receive a message from him inviting them to join my site.
I look at this link: http://developers.facebook.com/connect.php#Basic
Every tutorial I look at just talks about the SHARE button. How to make a user send an invitation to friends of his friends
