For store games, I don't have one, other than "doesn't piss off the regulars nor violate the safe space rules of the store." But that's store rules, anyway.Was reading another thread where a DM mentioned players passing their vetting process. If if not formalized, every DM has a vetting process. Generally, you need to limit the number of players in a campaign. I'll write up some of my thoughts of how I vet players for my games and experiences I've had on the player side. But don't wait for me! Share your thoughts on what works--or doesn't--for vetting players.
