title: Send Message to users inbox using PHP based facebook apps
body: <p>I have created an application which can post to users wall or even send emails to selected users, what I have not been able to come up with is the functionality to let an application send a message to users facebook inbox, I have googled it and found that applications are not allowed to send messages to users inbox however there's this product called rockmelt browser which does the same thing.</p>
  
  <p>There's has to be some way which allows sending messages to users inbox.</p>
  
  <p>Can somebody guide me on this?</p>
