title: how to overwrite drupal default message when posting comments?
body: <p>I would like to overwrite a default message for posting a comment. </p>
  
  <p>For example, I would like to display "<em>Your comment has been sent to the site moderator and will remain private.</em>" instead of "<em>Your comment has been queued for review by site administrators and will be published after approval.</em>"</p>
  
  <p>I tried hook insert, but it didn't override the message:</p>
  
  <pre><code>function custom_comment_insert($comment) {
      //drupal_get_messages(null, true);
      unset($_SESSION['messages']);
      drupal_set_message(t('override like this.'));
  }
  </code></pre>
