Actually Enigmail couldn't generate user's key (I wanted to do a clean install and see the provisioning process for normal users) and later got stuck on some silly, completely unnecessary step (generating revocation certificate).

As for PeP I don't quite understand how it works and what is it for (and I'm quite proficient with OpenPGP in general). I don't mind Autocrypt, it's good for people on commodity mail providers, but I rather prefer Web Key Directory where possible.
