Crum is pretty cool.
But you may want to check out a thread that shows human populations in each World at each level.
Also, some Worlds seem to be more active by division... like at one time, Naismith was considered to have a strong Div-3, and Wooden was the place to go for Div-2. Not sure if that is still the case.
