Full Library of Challenges

CTF organizers have full control over the challenge set for their CloudCTF instance. They can add, remove, edit, or hide challenges at any time before or during a competition. CloudCTF also provides a library of challenges; organizers can create their own challenges, use pre-existing ones, or both.
