Panzer8 has indicated that he's moved to other ideas.
When I sought to reboot things he told me (27/12/18):
"Hello Bob,
pardon me for the late response, but I don't check often this e-mail address (actually I do it very rarely).
I am not anymore interested in the Pz8 rules series...
I added you as admin (I hope I did it right) so you can manage the forum.
If I remember correctly there were not other relevant files in the yahoogroup.
The original Pz8 two pages rules are still available on the web

There is a French translation of the WW1 rules called Marmitages that added a lot of variants, expansions and scenarios Page 4 made by a French wargamer.
