I looked at the latest manuals both online and off here on the VM site. All documentation refers to VM 1.1. Where is the documentation for VM2?
All we have is in the Wiki at http://dev.virtuemart.net/projects/virtuemart/wiki
Also see http://forum.virtuemart.net/index.php?topic=96325.0
A book about VM2 has, I understand, just gone off to the publishers for printing.
