How do I add a student to duolingo?
I have tried everything in the guide. Nothing works. I had a student in one of my classes who needed a simple password change. I kept trying different passwords that were not accepted. Finally in frustration I deleted the student's account. When I try to add him back in, he doesn't show up on the class list. My students do not have email addresses. I tried using my own address with his name and that only confused the issue. Had to delete myself off the class list. What gives here anyhow?
