Randomize, the casts are getting too repetitive...
What needs to happen:
-People can't join for six months after they join (unless they get 15th-16th, then four months).
-Enrolment drops to Black level...I know may great Black levels who deserve a shot!
-A Stars for people lower than Black, which is more basic (only 10 people, perhaps?) based on votes that week (on a mod's blog?), trends, karma...Whatever. :)
