After the course page has been started, instructors and ambassadors should add themselves in their respective roles in the Summary section.
Students should be given the URL of the course page along with the enrollment token. They can then sign up as students in the course (once they have created their Wikipedia accounts).
The students should enter the article(s) they are working on to the Students section of the course page, as well as their classmates' articles that they will peer review.
Use the Special:MyCourses page to see recent activity from your students. This feed can be linked from the top of the page near your username as "Courses". You can enable or disable the link by going to Preferences > Misc and selecting "Show a link to your courses at the top of every page".
