#   NOTE! default-key is used instead of local-user as the latter cannot be

# Trust On First Use (marginal trust) with WoT being full trust. I find this
# less annoying in KMail than only WoT or the comment below, and I think it
# may be additional motivation for me to actually sign the keys I trust with
# all keyservers hiding signatures and gpg not importing them.
# I think `keybase pgp pull` also helps here as the people I am tracking
# there are going to be in my keyring, however it's still a centralized
# service.
