I've run a Box PASS or 2 and found the following good ways to start -- set up and publish your list of sticks that start off the PASS -- name the level of PASS you are trying to run i.e., Habana Only, Super Premiums, Domestics Only, Dog Rockets, etc. ---- what type of experience and references do people need to participate in your PASS?
I have found the most critical thing in any PASS is the makeup of the people in it.
Good Luck,
