They way that I originally organized the Home Server articles didn’t work because the menu would fall off the screen and you could not select all the articles anymore. To fix this I decided to insert another menu level in the tree. Unfortunately this has the effect almost all pages in the Home Server series now have a new url. I guess it takes a few days before all search engines catch up with these changes.
The menu system itself is changed too, I have now more control about what is displayed in the drop-down menus and the titles of the pages. This should make navigation a bit more friendly.
