We're launching our "Challenge Your Friends!" section today.

You'll now be able to make and share your own coding exercises with your friends, and then sit back and track how well they fared via a nice dashboard.

There's a list of over 200 coding exercises in our free catalog to choose from to get started, so if you're feeling lazy and don't want to come up woth your own challenge, just use one from our catalog.

These challenges are also a great way to screen candidates for your job interviews in your company!
