We are aware of an issue where some faculty are missing some, or in a few cases all, of their previous courses from the Spring 2017 semester and earlier. The courses and all of their content still exist, but your role as the "Teacher" of the course in Moodle simply needs to be re-added.
We are working with our vendor, eThink, to get you listed back as teachers on those courses so you can regain access to your old content.
