For anyone interested, ClanBase opened the signups for their Spring 2013 3on3 Elite Cup. For more information see their cup page: http://clanbase.ggl.com/news_league.php?lid=13120
There is no price money for this first cup but if it's a succes (lots of clans join and high level of play) they might be able to find sponsors for the next cups
So let's all join and have a lot of fun!
