Improve how we link to the Code of Conduct from our communication channels
Originally created by @sajolida on #16781 (Redmine)
Our Code of Conduct is linked from the /listinfo pages of our mailing list, like in: https://www.autistici.org/mailman/listinfo/tails-dev.
But the listinfo page is not itself linked from our website. I also doubt that many people read these pages anyway.
I think we should also:
- Link to the Code of Conduct from the welcome messages sent by Mailman.
- Send reminders of the Code of Conduct periodically on the mailing lists.
