Private message prefill message body I'm using Drupal 7 Privatemsg module.
To prefill the message body, I use the following hook but don't get anything displayed.

function MyModule_privatemsg_message_view_alter(&amp;$vars) {
  module_load_include('pages.inc','privatemsg');

  $vars['message']['body'] = "&lt;i&gt;Dear Friend&lt;/i&gt;,\n &lt;strong&gt;you rock!&lt;/strong&gt;";
}


Any help ?
One solution is to use the Prepopulate module and then customize the URL to send a privatemsg.  This works well if you are using Views to generate the links, for example.
