Where can RSS Graffiti post to?
RSS Graffiti can post to your profile wall/timeline, pages, groups, & events. Almost any Facebook page to which you are allowed to post is available as a target. There are only a few exceptions; you cannot use RSS Graffiti to post to pages which you do not administer or to profiles which are not your own.
We are looking into possibly adding a feature that allows publishing to other platforms such as Twitter or Google+ in the future, but currently RSS Graffiti does not support posting to targets outside Facebook.
