From the announcement:
Dust-League.Com is proud to announce the start of the first Dust Games Leaderboard. Any games of Dust Tactics and soon Dust Warfare that you play at a registered event will earn you points for the Leaderboard.
The Worldwide Dust League website keeps track of the results of games played all over the world. All you need to do is fill in the simple results form and we will do the rest.
As we go forward we will be adding more content beyond listing results, upcoming tournaments and interviews.
