Oh, I love questions. :D
To have a league, you have to PM me (or any other Wifi Mod: Horizon, Erik Destler, Aurafire) your draft of your opening post. I (or any of them) will either:
- approve of your league and you can then post it in the Battle Stadium forum
- help refine any issues or offer suggestions and later you can post it
- reject your league because of unoriginality or lack of organization
