I've encountered two problems one is connected with posting messages on wall and the other concerns creating events on fan page. Is it possible to post a message on fan page wall as a fan page not a admin user ? Can I programmatically create event on fan page (not as admin but as a fan page) using Facebook C# SDK ?
