(By the way, did we ever completely finish the last challenge chain? I remembered that it got stuck when a few people dropped out... I'd recommend maybe setting some expectation in place beforehand, for example that you have 1 week to reply to your challenge to at least acknowledge that you are planning to complete it, and if someone isn't able to complete their own challenge yet, they can still go on to issue a challenge to the next person on the list. That way, we could at least keep the challenge moving faster and ensure that the people at the end of the challenge still have a chance to play.)
