Variante von AhA
- Nur angemeldete Benutzer dürfen Seiten hinzufügen
- Erstellt wird automatisch eine Unterseite des angemeldeten Benutzers
- Schreibrecht nur beim Benutzer
- Exisiert die Seite bereits, erscheint eine Fehlermeldung
- Der header ist global
- Gibt man in der Seitenvorlage (zum Beispiel am Schluss) ::: ein, werden diese drei Doppelpunkte bei der Übergabe durch vier Doppelpunkte ersetzt. Wenn der Benutzer seine neue Seite erstmals editiert und wieder speichert, werden die vier Doppelpunkte durch den Benutzernamen ersetzt -> backlink!
- Wenn kein Seitentitel eingegeben wird, bleibt die Aufforderung, man solle einen Seitentitel eingeben
