I am a graduate student instructor at Berkeley CED and I am trying to use Miro to display/review some of my students' work. I have 19 students in my class, however I can not give them all the power to edit the board. Last year I had a smaller class size so maybe that is how I was able to let everyone have permission. Is there a way to add more seats or will this involve payment (I don't have a teaching budget so I would probably move to a different platform)

Thanks,

Natalee
