Beautiful! I was trying to add user roles to that list and added “author”, thinking I’d be able to show the gradebook for both subscribers and authors.
This works fine for me; my users needing a gradebook will all be authors.
I’d recommend some functionality that might allow choice of features different user roles might have for a gradebook. Here I’m thinking that an instructor and TA might both have access see and write grades/assignments, though one would be administrator and another might be an editor. Students might also have different levels of access.
