Thanks a lot for the welcome and the useful userhelp files.
I'll check them (looks like a lot). Going through the stuff in the coming days.
I'll still ask the question in general if someone can help me through some kind of chat of ideally for instance through a longer phone call through whatsapp. The best way to learn is probably to go hands-on.
I only know 1 map and that's from the boardgame. I have a version that is at least 30 years old (spring 1942). But seldom played it lately.
I am interested in playing online and would like some advice as to which one of that long list of versions is most played. I guess that will be my best chance of finding 1 or more players to play with.
I'm also interested in giving a game by mail a serious try.
