Yeah, I knew that, it's super cool, and it came to mind as I was writing my earlier comment.

What's neat about the website stuff is that even if it's not as good now (idk, I haven't looked), that value they created is still there in the older case study — there were so many good resources. I was the disability rep in a few student societies, as well as in a few volunteer orgs after uni, and we referenced the guidelines a few times. Good resources like that are especially useful in those contexts — because they helped turn "that would be nice, but we don't have the resources to implement accessibility in our materials" into "okay, let's put our money where our mouth is and do our best to make something as accessible as we can"
