I submitted my project but it says "Awaiting moderation". Will it affect my eligibility?
As long as you submit your project before the deadline it doesn't matter when it is moderated. Just sit back and enjoy a well deserved break!
My project is locked and I can't edit it anymore. Why is that?
All projects entered in the contest are locked after the submission deadline to ensure that they remain the same during the judging process. They are then unlocked after winners are announced.
Somebody copied my entry! What can I do?
When judging entries, we take into account the submission date. When an entry is clearly plagiarized from another, we favor the original entry. If you believe the result of the judging is unfair, please email us at to appeal.
