Be capable, be a teammate, use a voucher, you cheap shit.
This is an association for gentlemen (ladies also quite welcome) who have the following traits:
1. Don't suck at MvM. Seriously. Don't waste our fucking time teaching you how to play.
2. Are willing to use vouchers. It's nice to be generous!
That's it. Invite friends who have these qualities, and that way we can always have someone to take tours with.
