A collection of creative challenges, organized by topics. Within each topic, participant can choose the ones to complete. Each Challenge has a difficulty rating that any site visitor can enter a rating of their own (crowd sourcing the difficulty rating).
Responses for a challenge must exist at a public URL; people who complete them enter their information in a web form (including a tag that can identify them as the author) so that the responses are added to the challenge itself.
Participants can also add new challenges to the site so it can grow. We envision making a special category for “Re-Challenges” where participants may create a new challenge from an example or as a remix of another challenge.
