The Zodiac Club began with simple guidelines
- There could only be 12 members in the club at one time.
- Each member represented a Zodiac sign, which was inherited from their predecessor by death or resignation.
- Resignation was only for those with ailing health or those who were too old to participate.
- New members had to be unanimously supported by the other 11 members.
- New members were invited to dinner.
- Each month, one member was the appointed "caterer" who organized dinner.
