Folks here may be interested in this: Free code of conduct enforcement book available now. The focus skews towards volunteer-led tech communities and conferences, but may be helpful to anyone leading any community with voluntary membership.
Thanks for that link.
For anyone who might not read the download page, the request for an email address can be ignored as the author provides a direct link on the same page.
The book is not as useful as I expected because it focuses on enforcement without fully integrating the positive influences of a Code of Conduct into the enforcement regime. In other words, how can I use a Code of Conduct to, first, have purposes beside providing a baseline for determining what should be enforced and, second, to minimize the need for enforcement.
The author present circumstances where “… your community is better off without a code of conduct.” I disagree.
