There are local events (usually held in your neighborhood SDMB coordinator’s basement) in which you can compete in certain trials. The survivors are allowed to continue to the state and then regional tournaments. Then super-regionals are used to winnow out the weaker contestants so that only a favored few can compete on a national basis.
So, you have to ask yourself, “Self, do I have what it takes to become an SDMB moderator? Well, do I, punk?!?”
Good luck and remember, that waiver will stand up in court. Trust me on this one.
