Does Ultimate Facebook Allow New Users to Subscribe Via Facebook?

Hello - it is unclear with the description and the installation instructions of Ultimate Facebook if it will work for a new user to subscribe to my site via Facebook.

The description reads "This one stop, do-it-all Facebook plugin makes it easy to integrate just about everything that is possible between your WordPress site and Facebook."

I wasn't sure if the plug-in was just going to work for my facebook account or if the api created via my facebook account allowed people to subscribe to my site and be able to use the different features of Ultimate Facebook.

Please let me know if this is the correct plug-in to use or if there is a different one that I need to get.

Thanks!
