We could perhaps add defadvice to **wiki** for those who want to do global change in their emacs environment, something like: (if (< emacs-major-version 25) (defadvice mml2015-epg-check-user-id (around downcase activate) (ad-set-arg 1 (downcase (ad-get-arg 1))) (ad-set-arg 2 (downcase (ad-get-arg 2))) ad-do-it)) totally untested -- also now that I finished that 'before might also work.
