So I do not know much about codes of conduct. I know they're old hat but I don't have personal experience in interacting with them. Are there any "off-the-shelf" CoCs other than the Contributor Covenant I should be aware of? It seems like it's better to use one that's met with success elsewhere than to try to write your own but the Contributor Covenant is the only one I've heard of.

@mhoye In your opinion is there an argument for using CPG over CC (or vice versa?)
@mcc Not really. I can nitpick, but the specific text of the CoC anyone picks is far less important than having a principled enforcement process, with teeth and a spine. The text is just velvet-rope crowd management, the actions of the people running enforcement are going to be where your real CoC is born and raised.
@mhoye @mcc this reminds me of something some said years ago… “culture isn’t what you support. It’s what you tolerate”.
