Fantasy Baseball - Where do you play?

Looking to join a fantasy baseball league and am open to suggestions from others. Whether it be a hardcore league or one for casual fans I see pros and cons for both. Just wondering where others play and what they can tell me about their leagues? Or perhaps someone who has a established league looking for others this year might give me info on their league? Any and all info would be helpful. Thanks in advance!

Couple of leauges forming here on Yahoo for free. Probably semi-serious, but not too hardcore.
