Hi.
Accoding to "What is Faithlife?" it is an online community with an implied emphasis on connecting church groups and school classes, as well as addressing commong security concerns some people have about other social networks.
Besides this, have you worked out where you want to go with the project, and more importantly how it is going to be different from facebook? What will it accomplice that a facebook app will not? Because lets face it, At this point Faithlife sure looks and feels like a stripped down version ( with the addition of the Amen button :-).
