Leagues are a great way to maintain healthy competition between rivaling classes, schools, regions, and even industries!
You can set up a league for your family, friends, coworkers or school to watch how your fellow league members are performing. You can even set up several leagues and track them to compare league versus league. This is a great tool for teachers who want to compare just between their own classes or between a group of teachers who wish to compare class to class. Who will be the top sleuth?
