@FediFollows @Fairphone @protonvpn @ProtonCalendar @protonmail @1ll173r47 For expert-to-novice, if it's long term w/frequent contact, I use mutt & pressure the other user to use electronmail, & I walk them through putting my pubkey in their address book & exporting their key. That's rare though. Most often I can't get away w/imposing that burdon on them, so I have to use electronmail & i'm happy enough just to get them on protonmail.
