Erweiterte Diskussionsseiten

Verwendung: In der eigenen monobook.js die folgenden drei Zeilen einfügen:
document.write('<script type="text/javascript" src="' 
     + 'http://de.wikipedia.org/w/index.php?title=User:Magnus_Manske/ED.js' 
     + '&action=raw&ctype=text/javascript&dontcountme=s"></script>');

Man kann das Verhalten den eigenen Wünschen anpassen, wenn man VOR DEN OBRIGEN DREI ZEILEN folgendes einfügt:
ed_absteigend = 1 ; // Diese Zeile einfügen, wenn Diskussionsseiten standardmäßig absteigend (d.h. letztes Thema oben) sortiert werden sollen
ed_letzte = 2 ; // Hier werden standardmäßig die letzten zwei Diskussionen angezeigt (alle anderen verden versteckt)
ed_edit = 1 ; // Auch in der Vorschau beim Bearbeiten

ed_ausserdem = new Array () ; // Eine Liste von "normalen" Seiten, die auch entsprechend angezeigt werden sollen
ed_ausserdem.push ( "Eine_normale_Seite") ; // Ein Beispiel (wichtig : "_" statt Leerzeichen!)
