We’re now taking registrations through Google Forms. (Thanks, Jennifer Crow, for the suggestion!). Each course detail page now has a link to the new registration page. Now you can register each enrollee for multiple courses at once, rather than having to fill out a separate form for each.
Meanwhile, you can still download the Code of Conduct forms as before form each course description page. These can be printed, studied, signed, and submitted on the first day of class.
