Anyone can write a thread or a post. Any post or thread can potentialy be nominated. Each week our staff goes through all posts and threads of the week before, and we choose around 10 which we consider to be the best threads/posts of that week.
Those chosen will then compete in a $100 private freeroll for the ocasion.
You can see each week's nominated posts here:
