Points
You can only 'win' points by participating to the monthly contest. Other users will vote on your submission, the amount of votes you get will transform into Points.
When a user with level one, who's got a Voting Power of 1, votes for your submission, you will 'win' 1 Point. When a user with level two, who's got a Voting Power of 1.25, votes for your submission, you will 'win' 1.25 Point, and so on.
NOTE: Voting Power will generally increase by .25 points per level. (It�s a bit irregular)
