Can't create account --- Invalid username
My students are really getting frustrated on trying to make an account and I am sharing their pain. It’s not letting students put in a username. It keeps saying it’s invalid. Geogebra initially defaults to automatically loading the first part of their school email address first.last as the username. That appears to be invalid due to the "."
Geogebra does say to use alphanumeric characters. After trying many different variations, it appears that spaces aren't allowed either. If this is the case, there should be better wording on username restrictions. I had a lot of students just give up because of their frustration.
