For security reasons, we don't just give people access to old Stellar sites. They should check in with the Instructors, Admins, and/or TAs first and ask for access to the course. Note that this does not give them access to homework submissions materials; we will need to get permission from the professor to unarchive the course.'
If no one is present in the department, these should be handled on a case-by-case basis of giving access. If someone (e.g departmental admin) can be contacted, this is preferable to us giving people access.
