It would be great if Lumio would allow a student share link so students can access the lesson without having to sign up. My school system is not allowed to ask students to sign up for anything, so this makes it difficult to share the student link to the Lumio lesson when a student is absent because in order for the student to view the link, they will have to sign up. Can this be changed so students can access the shared link asynchronously without having to sign up?
