It will all be decided on Random.org. You can apply for any season when it comes about.
When it comes time for All Stars, there will be some few major differences:
1.) I will announce All Star Rules as the season begins.
2.) All Star queens will be alerted to check the proper forum for their cast reveal!
3.) If I feel that the group is active in seeing the game progress, then there may be some changes in the format!
These rules and limitations can change depending on different seasons or other real life factors, but will keep it posted when this stuff comes about!
So everyone, start your engines, and may the best contender, win!
