ChallengeBot is a tool that combines a bunch of my adhoc scripts and tools from the last few years I've used for managing and sending out coding challenges. It handles invites, scheduling, time limits, Git repository hosting and progress tracking. It's made my life a whole lot easier, so I figured others may be interested as well. And you can try it without having to sign up for an account!
