I think that Worldember should have an opt-in feature. Maybe it could work through an option in world settings which users can turn on/off for each of their worlds? In current system we see that in every Worldember there is a number of people who probably aren't taking part in the competition, but still appear high on the leaderboard because they are doing RPG or Novel stuff which quickly brings them to 10k words.

If this isn't an appropriate place for raising such issues I'm sorry
