title: facebook send dialog prepopulated with text
body: <p>I am developing an application where I want to be able to send messages to friends.</p>
  
  <p>I want to display a list of friends and besides each friend there is a button which triggers the send dialog. </p>
  
  <p>But I want the dialog to be prepopulated with the friends's name and a text like: I want to invite you to this event..</p>
  
  <p>How can I do this?</p>
  
  <p>PS: I am not intending to send messages to multiple users at one time, as this is not possible. For each message sent there will be necessary the user hiting the send button</p>
