If you are interested in joining an existing H2H set-up, come and play the H2H World Series. I'm the commissioner of the UK league, and am always looking for new players. There's loads more info about it in this thread:

It really depends on exactly what you want out of your league. I thnk the best site out there is sportsline.com. You will have to pay there though. If your planning on running your own league you can use the Baseball commisioner on sportsline. It is very flexible and you can customize your league to your liking.
