As you may already be aware, Spring 2021 full-semester waitlists were purged in error this morning. Students who were purged from a waitlist no longer have access to that class's online materials and are no longer on the roster.
We are currently looking for ways to restore this information, if possible, and will communicate with affected students when we have more information.
In the meantime, we've temporarily disabled students' ability to join a Spring 2021 full-semester class waitlist, and have added a notice to relevant webpages, including our homepage. Departments may request a waitlist purge report to view affected classes (email cusisdev@colorado.edu).
