When does the next league start up?

Well, I downloaded the rule book, I bought a set of NAF dice, I just got my Dwarf Bloodbowl team today, and I got a case to carry them in, so when does a new league/learn to play gig kick off? I'll need a couple of weeks to paint my guys up, but other than that I'm ready to learn this game. Oh, and if someone happens to have an extra ball for sale (or to give away!) I'm interested. Thanks!

One other thing. Is there a US source for felt bloodbowl gaming mats? And I just signed up for the Four Diamonds cup, it looks like it'll be a lot of fun!
