Sorry to nitpick, but maybe suggest "LastName_Wk2" as the example. Also, maybe differentiate between viewers (who can comment) and editors (which seems odd for instructors tbh)

Many instructors want to provide detailed feedback, duplicate cells, add code, and control sharing if they need to - it's easier to tell students to make them editors to cover all bases than rely on students changing the settings again if a teacher needs access. Most teachers are editors and this instruction was lifted from Mike Freeman's class... Viewers are described elsewhere in the collection so I can link to that.

I guess this is basically duplicated here? Whichever version stays, it should definitely have the fork link and maybe a brief explanation what that means (not exactly common outside of computer science)

Yes, duplicated since it's a common challenge for teachers and I wanted to make sure they see it if they don't start at the beginning - some of the re-organization you suggest might make this more seamless. Def will define forking more explicitly
