Allows users to tag private messages and to filter based upon those tags.

Code

function privatemsg_filter_get_filter($account) {
  $filter = array();

  // Filtering by tags is either allowed if the user can use tags or he can
  // filter.

    if (isset($_GET['tags'])) {
      $_GET['tags'] = urldecode($_GET['tags']);
