Back to Normandy has been updated, because of security reasons, mobile use and new technology and because of a new approach of presenting the thousands of records to the visitors. The forum is temporary disabled.
A great part of the content has been moved to other places. For example you can find all the divisions in one directory depending of the type of division (infantry, armored or airborne). But be sure, all the data were you looking for is still available. And of course there are new updates!
It will be more fun to explore Back to Normandy with the tens of thousands of records about WWII.
