title: How to write a TeamCity notification plugin which will execute with no subscribe users
body: <p>I'm trying to write a plugin to handle notifications via a third party app which runs on iOS, Android and Windows phones. The app itself handles the user subscriptions, TeamCity does not [need to] handle the subscriptions.</p>
  
  <p>The TeamCity plugin docs say:</p>
  
  <ul>
  <li>Notifications are only delivered if there is at least one subscribed user for given event.</li>
  </ul>
  
  <p>The api has methods which include a collection of subscribed users:</p>
  
  <ul>
  <li>public void notifyBuildSuccessful(SRunningBuild sRunningBuild, Set sUsers);</li>
  </ul>
  
  <p>How can I get TeamCity to call my notification plugin even though there will be no users registering as plugin subscribers through TeamCity itself?</p>
