These are the people who make CodeWars happen. An incredible amount of time and effort is spent every year (usually starting around August, and finishing just before the contest starts) writing problems, testing them, coding solutions for them, and testing those solutions. We also have a volunteer army of people who arrange food, get chairs, tables, hook up electricity, setup the networks, and arrange for prizes and trophies to be given out at the contests each year. Without these volunteers giving of their time and skills, CodeWars wouldn't happen.
