Skater classes are meant to classify the skating level of each skater in your league. From beginner to advanced.
Why Do I See Lots of Different Types? - We thought it best to add the ability for any manager of leagues to add more skater class types. This should allow for a better way to group think how to manage Roller Derby Leagues. If one League has been doing an excellent job of classifying their skaters, then why not share that way with everyone. So before you create your own class, be sure to review the classes already available.
