My dad could use a helpful resource on establish a baseline community code of conduct for an online discussion group. Any recommendations for good guides and/or templates?

(This is a •completely• nontechnical group, FYI.)

@inthehands I'm a fan of the Contributor Code of Conduct (https://www.contributor-covenant.org/version/1/3/0/code-of-conduct/) which I think could be easily modified for an online discussion group. Just replace "project maintainer" with "moderator" maybe and update the opening sentence and a couple others.

The most widely adopted code of conduct in open source. Stewarded by the Organization for Ethical Source.

@inthehands Our instance has a good one that we work shopped and voted on: https://wiki.neuromatch.social/Code_of_Conduct

ETA: some of it might be a little too specific to here, but overall the gist is probably what you want

@inthehands I have a draft code of conduct that I can share. DM me with an email or Signal ID.
@inthehands Here's one from a Slack community I just joined.

@inthehands This is for a local conference I used to help organize. I like that it puts values first (the "why"), then details mechanisms. Note the CC BY-SA license. https://minnewebcon.org/code-of-conduct.html
@inthehands Keep it simple and make participants agree to it BEFORE participating, if possible. How about "Debate ideas, but personal attacks will be sanctioned, including possible expulsion. Don't break the law." Those are examples of simple rules, but you should separately make clear how breaches will be adjudicated and sanctioned.
