Help me get the Dementor Crystal Ball playing this game!!

Hi there!

There is a HP tournament where I could win the Dementor crystal ball, the second prize is the entire set of movies and the third is a mug (or whatever ) .

The tournament is free but it will not start unless there are 400 participants before the 17th, so please please join or share it as much as you can!!

[You must be registered and logged in to see this link.]

I promise to let see you all the Dementor ball if I win it!! haha
