Hi, Tzviya, Bill– Thanks for the feedback. I've added the Instructor's Manual scenario [1] to the use case; please edit it to correct any mistakes I made. I agree that this is a good addition for a formal publication perspective. I do think that the "production workflow" scenarios are also valid and useful, especially considering how much the Web has become a medium for collaboration. It's good to get a variety of perspectives to make sure that the requirements fit a general use case.
