Autonumbering of pages
This is setup per category in the site manager.
This is useful if you want to split the "page title" from the primary key-numbering in the "page-name":
you have to setup this feature in the Site manager in the menu "autonumbering of pages" :
Tip: you should name the used category for such autonumbering WITHOUT any special characters like "-"! Numbers are since last changes not disturbing.
