Oh I thought you wanted his personal email. I have a correspondence someone else sent me that they had with him about it. I'll have to check with the person who forwarded the email exchange and if they're cool with it I'll pass it on.
Mainly about his upcoming volumes and the contents (he's working on Volume V right now and he shared with me all the contents, which aren't available on his website), his other plans (addendum on logistics), his response to the TIK's video, his current occupation and a bit on Lend-Lease effect, Soviet fuel production during the years of war and some draft on chances of Barbarossa success (that interests me the most and I'm waiting eagerly for his last volume with the results of simulating early drive on Moscow).
