Share Programs in JoostConnect – JoostBook
I have added the ability to share any video in your favorites, or your history with your friends. You can send invitations to all of them, or just a couple.
The only downside to using facebook's invitations is that lots of users will probably not notice their invitations unless they are really on their profile. The invitations show up along the right gutter when looking at your home, or mini-feed. If you are like me, and you have tons of invitations, you may not even see them.
