Student problems to join a group
Some of my students had problems to join a the group I created for them. We have not used Geogebra before, so they were asked to create an account. The problem for some of them was, that when they created the account they had to wait for a sign in affirmation email, but it did not came and they could not find it in their spam either. I tried to send some invitation emails as well and not all off them came through. Thank you for your help. I really would like to have all my students in the group.
