title: Can I delete a message with Facebook API?
body: <p>I want to delete a specify message such as selected by user. But SDK returns "Uncaught GraphMethodException: Unsupported delete request";</p>
  
  <p>$mid = (message_id get by FQL);<br>
  $facebook->api('/'.$mid, 'delete');</p>
  
  <p>Is there how to delete a message?
  (Incidentally, an event can delete by this method.) </p>
