We've made a change in Moodle in response to your requests: We've set courses from previous semesters to be 'not available to students' (as Moodle labels the setting). This removes those courses from students' view and sorts them to the bottom for faculty. ADCP courses and courses for which students are still completing work are excepted from this change. We plan to repeat this setting change each semester in the future.
Faculty may undo this change by visiting 'Edit course settings' and changing 'Availability'. For assistance, please contact the Helpdesk at firstname.lastname@example.org or x4357.
