Brotherhood of the Ring Rules are auto-correcting. If you do something different from the rule, that then becomes the rule. The Brotherhood is politically correct, being also a Sisterhood.
By-laws are very specific....you have to have either built a Ringmaster, or flown one, owned one, or seen one, or perhaps dreamed of one. Or you may have read about one, or knew someone who did....
One noted flyer who publically eschewed the venerable Matt Kania design found an aged but well-executed Ringmaster in the gutter as he drove to church, which he picked up and donated to a charitable cause. Bingo! He's in! I cannot bring myself to conclude that's happenstance, can you?
Having met this criteria, you become as one with the Brotherhood, with a little luck, you may be allowed to become a member of the "inner circle", allowed to flaunt your esteemed station in life as demonstrated by the secret handshake.
