Adding existing Duolingo users to a classroom
Apologies if this has been asked and answered elsewhere.
I have been using Duolingo in my school for some time, certainly before the teachers' dashboard feature.
Now I'd like to get existing Duolingo users to join various classrooms. The trouble is that while many used their school email account to register in the first place, others didn't. It's going to be a massive task to try to establish which email addresses to send the invite link to. However, I don't want to have to create new accounts for pupils who have been working hard.
Is there a way around this?
