* Kevin Fenzi:
Yes, you absolutely can interact with discourse via email (mostly).
This option has been disabled in the Fedora instance, though. There should be “Mailing list mode“ and “Enable mailing list mode” at the end of this page:
https://discussion.fedoraproject.org/u/fweimer/preferences/emails
But in my case at least, it's missing.
Thanks, Florian
