There is a new collaborative website for Diversity, Equity and Inclusion that I have just set up.
You can access it here: https://practical-dei.github.io/collaborate/
This is just a barebones site, but I am hoping that I can find a way to populate it with anyone interested in making a contribution.
One of the ideas is around a Diveristy, Equity and Inclusion hackathon. You can see it in the issues register.
Think of it as a focused wikipedia, although it is probably more difficult to navigate for people not used to github and markdown.
You can look at the introduction guide, or reach out to me if you would like to contribute.
