Connecting to pages
You will need to use a Facebook account that has a Profile with administrative rights to the Page. A Page-only account can not be used with Publicize. See the Facebook Page-only Accounts section at the bottom of this page for complete steps on how to check for this and how to add a Profile to your Page.
RSS Grafitti can be used http://www.facebook.com/RSS.Graffiti for posting to Facebook walls if you prefer. RSS Graffiti periodically checks the RSS/Atom feeds that you specify and posts any new entries it finds to the Facebook Walls that you specify. You can get any feed written on any wall (Facebook Profiles, Fan Pages, Groups, Events and Application Profile Pages). In fact, multiple feeds to multiple walls. You choose the combination.
