My team is now thinking of buying Miro subscription, but there’s a few questions that we can’t find an answer to. Could you please help us?

1. Is there a possibility to import Mindmeister mindmaps into Miro?
2. We need editor’s access to mindmaps for <10 people, and unlimited sharing of maps for viewing it with our students (500+ people). Is it possible with the subscription for 10 people in the team? Which subscription type should it be?
3. About the students, which are “visitors” to our maps. How many maps will they be able to open (view mode) without registration in Miro? Is there such possibility at all?

Thank you!
