Hmmm, maybe I should have never 'linked so deep': Notice: Undefined property: SkinVector::$mTitle in /home/jidanni/mediawiki/LocalSettings.php on line 55 Fatal error: Call to a member function quickUserCan() on a non-object. The code that used to work was: $wgFilterCallback='JidanniTitleFilter'; function JidanniTitleFilter($mTitle){ if (preg_match("/^\d/", $mTitle->getText()) && $mTitle->getNamespace() <= NS_TALK) EditPage::spamPage ('***請退（"←"鍵），另存所打的字，然後見「首頁」=>「使用說明」中之「頻率編入其單位」。謝謝。***'); return true;} return false;} Maybe I should just say in my message 'if the page you were trying to edit was a talk page, then ...', instead of trying to determine it myself with the ever changing internal parameters.
