In order for the SFC-Publish plugin to be able to publish your posts automatically, you must grant some "Extended Permissions"
to the plugin.
Offline Permission is needed to access your Page as if you were publishing manually.
Publish Permission is needed to publish stories to the stream automatically.
Fan Page Publish Permission is needed to publish stories to the Fan Page automatically.
User ID and Session Key found! Automatic publishing is ready to go!
Be sure to click the "Save Settings" button on this page after granting these permissions! This will allow SFC to save your user id and session key, for usage by the plugin when publishing posts to your profile and/or page.
Why would you put private posts on Facebook, for all to see?
