A challenge is a bite-sized creative prompt for particular creative interests (like Writers, Illustrators, Video Editors, etc.) Anyone can issue a challenge, and anyone can contribute to one. So, if you’ve got an idea or a work in progress, and you want the community to jump in on it with you, issue a challenge. Make your title, description, and instructions unique and enticing. You can even record a challenge video so you can provide more context. The more specific you are with what you're looking for, the better the contributions will likely be.
