Accept an invitation to co-teach a class

Invited teachers get an email asking them to co-teach your class. To join the class, the invited teacher must click a link in the email, or sign in to Classroom and click Accept on the class card.

Note: A common issue is teachers not clicking the link and accepting the class.
