title: Posting on User's friend's wall with Facebook
body: <p>Is there any way to post something to a user's friend's wall from that user in my facebook app?</p>
  
  <p>Example: A user of my facebook app answers a question about one of his friends. I want a small message to be posted to the wall of that friend saying 'Bob answered a question about you...'</p>
  
  <p>Is that possible? If so, how?</p>
