Tweaks signatures in ways inspired by other traditional forum software:

Code

function signature_forum_pre_render_user_signature($element) {
  static $show_once_cache = array();
  $uid = $element['#user']->uid;

  // Apply show once setting.
  $show_once = variable_get('signature_forum_show_once_options', SIGNATURE_FORUM_SHOW_ALWAYS) == SIGNATURE_FORUM_SHOW_ONCE;
  if ($show_once) {
    if (isset($show_once_cache[$uid])) {
      if ($show_once_cache[$uid] == TRUE) {
        $element['#printed'] = TRUE;
      }
    }
    else {
    }
  }

  // Apply short content action.
  $short_content_action = variable_get('signature_forum_short_content_action', SIGNATURE_FORUM_DO_NOTHING);
  if (empty($element['#printed']) && $short_content_action != SIGNATURE_FORUM_DO_NOTHING) {
    if ($element['#content_length'] < variable_get('signature_forum_short_content_length', 0)) {
      if (!_signature_forum_user_exception($element['#user'], 'short_content')) {
        switch ($short_content_action) {
          case SIGNATURE_FORUM_DO_NOT_DISPLAY:
            $element['#printed'] = TRUE;
            break;
          case SIGNATURE_FORUM_ADDITIONAL_FILTER_FORMAT:
            $element['#signature'] = check_markup($element['#signature'], variable_get('signature_forum_short_content_format'), '', TRUE);
            break;
        }
      }
    }
  }

  // Set the cache, to show signatures only once.
  if ($show_once && !isset($show_once_cache[$uid])) {
    if (empty($element['#printed'])) {
