As an educator in higher education (College), we work on semester systems. The classes I need Mentimeter for only run for 15 weeks. A yearlong license is of no value if I don't have a use for half (or more) of the year. A 15- or 26-week options would be a fantastic option to accompany your educational pricing. It is hard for me to pitch a yearlong license when I don't have a yearlong class.
