In my case, if I were to belong to one of the half-a-dozen "offical" Matsubayashi Shorin-ryu associations out there I would have to have certification to run my school and all my promotions would have to be approved by the "money-grubber du jour." However, since I quickly got tired of the politics, i went "renegade". Hence, I do all my own promotions, and promote up to my current ranking. I'm sure this will be looked down upon by those in favour of associations. But I've found that associations exist mainly to feed the egos of those politically well-connected in said associations. End of my 3 cents
