  13          * This is a way of getting simple feedback from users. It's useful
  14          * for testing new features -- users can give you feedback without
  15          * the difficulty of opening a whole new talk page. For this reason,
  16          * it also tends to collect a wider range of both positive and negative
  17          * comments. However you do need to tend to the feedback page. It will
  18          * get long relatively quickly, and you often get multiple messages
  19          * reporting the same issue.
  20          *
  21          * It takes the form of thing on your page which, when clicked, opens a small
  22          * dialog box. Submitting that dialog box appends its contents to a
  23          * wiki page that you specify, as a new section.
  24          *
  25          * This feature works with any content model that defines a
  26          * `mw.messagePoster.MessagePoster`.
  27          *
  28          * Minimal usage example:
  29          *
  30          *     var feedback = new mw.Feedback();
  31          *     $( '#myButton' ).click( function () { feedback.launch(); } );
  32          *
  33          * You can also launch the feedback form with a prefilled subject and body.
  34          * See the docs for the #launch() method.
