One circle at a time
ArveClub opens a handful of seats at a time, so the floor stays quiet and the house knows every member by name. Leave an address. When a seat comes free the invitation goes to you, and to nobody else.
Keep this number.
It is how the door knows you.
No open sign-up and no public door. You are admitted, or you wait. The list is the only way through.
Seats go out in small groups. It keeps the floor quiet and it keeps the people on it worth knowing.
Eighteen and over. An invitation is personal and not transferable, and the house may decline without giving a reason.
