Hi @willamwatson1 ,
Does your school pay for Canvas? Are you using the free for teacher version?
Either way, there are a couple ways to view the people in your course. The first way is locating the 'People' button located on your courses side-navigation bar. Another way is by going to your course settings > sections and by clicking on the name of the section and the list of people will appear.
The last way to view your users is by adding /users to the end of your course URL. For example, the URL would look like this: schoolname.instructure.com/courses/344/users. Replace schoolname with your school's name, or with the word canvas if you're using the free for teacher edition.
I hope this helps, let me know if you have any questions!
