As a community we need a Code of Conduct
How do people feel about using on of the default options provided by Github?
Yeah, we need one and I'd use something simple and standard to start. We can always change it later if there's an issue, there are good chances that it'll never happen.
So if the GitHub suggestions look good to you (I briefly checked Contributor Covenant, seems ok for me!), please go ahead.
Just my 2 cents!
I find the code of conduct of Data Carpentry very inspiring: https://docs.carpentries.org/topic_folders/policies/code-of-conduct.html Obviously it has to be slightly rearranged as everything happens online in our case. If you all find it worth, I can do it and start a PR.
