Set end date for full proxies.
Many faculty only need a particular full proxy for one academic year, but there's no way in Ares to indicate when their access to the instructor's material should end. This is problematic for copyright and also because Ares addresses all emails to instructors AND their full proxies, which means proxies may get emails about all sorts of irrelevant courses after their work with the faculty member has ended. Having the option to set an end date (or end semester) would be very helpful. The full proxies could either be purged on that date or simply flagged for review.
