This app uses facebook connect to build a list on autopilot. You can sell this technology to clients or offer it as a freebie.

Very simply the way it works is you make the site visitor an offer such as a free download etc and they subscribe by clicking connect to facebook. As long as they click allow and a confirmation email link they are subscribed to your email client. The emails gathered are much more reliable and people are more likely to subscribe as the app automatically extracts their name and email !
