title: How do I set a customized message when sharing on Facebook using Addthis?
body: <p>I'm trying to set a custom message when sharing a page (via facebook) using the addthis module. So far, I've been successfully able to set a custom title, description and image (<a href="http://support.addthis.com/customer/portal/articles/381222-optimize-facebook-sharing#.UVkeSqspa0w" rel="nofollow">here</a> is the reference I used), but I also need to be able to set a custom message on the textbox where the sharer would be able to put in a comment.</p>
  
  <p>Is there anyway to do that using the addthis module?</p>
