Some good advice by Beercloud there for you. I recall my first league, not too long ago, I found the game a bit overwhelming. That said, I got speaking/messaging an experienced GM in GrandadB, and he was a HUGE help in getting me off the ground.
So, I might add that you get a kind of "mentor" of the game for the first month or so....it's not necessary, but it can be a big help. There are loads of experienced GM's that would be glad to help you out...as was the case for myself.
I'm not in the least bit experienced as others, but happy to answer any Q's you might have as best I can, just pop me or others a msg.
Enjoy the game mate, it is fun.
