I've just tracked back and realised that you mentioned starting with an empty project is a good idea in Ep. 3, so I got ahead of myself and went with an empty project, even though you select Web App. My bad!
This may also be what julioest has done? I could be wrong. Selecting an empty project will 1, not create the User.js file and 2, even if you copy it over, you aren't able to create an account to access that User.js file :/
