Ever wanted to contribute to #guix or #emacs commons ? A bit scary about the #email based workflow ? Afraid of having to manipulate thousands of emails locally ?
No worries: https://yhetil.org, a public-inbox based service, provides a nice web front end to browse for patches, issues and bugs you may contribute to fix: thread overview, outlining, reply links, thread download in #mbox format, everything you need to start contributing is there.
