The NAA is an anagram representing the "No Affiliation Association", an organization of unlike minded and extremely loosely affiliated individuals founded on January 10, 2010.

The hierarchy of the club is ever changing as their are no rules for entry and anyone may choose any position they like, with the understanding that titles mean absolutely nothing.
I guess they let anyone in the NAA, whatever, individuals unite!
