Those will be a great addition to this site.

Have user be able to create their own tournaments is great, and always give users a great oppertunity to play almost any type of tournament with many different time limits, user limites, BKR limits, etc....

But I believe with "Official" BK tournament, we will get some great tournaments since I think you will get more players to join those. And the possibility to get a "gold cup" after a tournament win is cool. Do you get a "gold cup" after each tournament win - some players could start earning a lot of gold cups!
