How do I message students who have not signed up for a self sign-up group?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). Depending on your Canvas view, your page design may vary from the images shown in this lesson. However, the functionality and location of the components remain the same.
If you have created a self sign-up group within your course, you can message students who have not yet signed up for a group and remind them to do so.
