Admins:
4 Admins will be "Heads of Houses", judges in the contests. Others will be regular teachers. Except the Headmaster or Headmistress.

Contests:
Monthly- The monthly contests would start with the submission phase of a month. At the end of the month, there will be a period of a week for judging, then the winner is decided.
Weekly- A weekly, non-Harry Potter themed "Story of the Week" contest would take place each week.

Class:
Class would be an RP thread, with one teacher, and a bunch of students. (We should have a thread to submit our characters to RP with. In that thread, we would say what year our character is in.) In the thread title it would say what two Houses are in the class, and what year. The class would have a couple phases-
Classwork and Lecture- The RP.
Homework- The thread will be locked when class is dismissed, and at the start of the next class, homework will be turned in (stories based on the prompts from the previous class), and your homework will be graded (reviewed).

RP:
There will be a Great Hall RP, and a Common Room RP (for each house), just like on Pottermore.

Credit to superpony55 for coming up with this by the way. I just tweaked the contest system a bit.
