I have to agree that there are groups, organizations, and federations that for the right price will give you anything you want. I, at one point, made the mistake of joining just such an organization (which I regret now) and that was due to my lack of knowledge about what was legitimate and what was not. I was thankfully introduced to several people who took the time to view my system and brought me into the organization I am currently with. I had to not only pass a review with members of the executive board, but also pass an intensive background check of myself and my father to verify any claims of rank, association, and instructors we had studied with. I also had to hold rank in a classical art of at least 5th Dan and at least Shodans in 3 others. It was quite exhausting but, well worth it to have my father's art legitimized under an organization that has the ability to recognize new systems. I also want to pass along my "credentials" as I was sent an interesting e-mail asking for them. I hold a 7th Dan in Shotokan, 2nd Dan in ITF Tae Kwon Do, 1st Dan in WTF Tae Kwon Do, 1st Dan in Washin-Ryu, 1st Dan in Kempo, and an instructors ranking in Kung-Fu. I hope that answers the question on credentials, and I have been involved in the arts for almost 31 years. Respectfully, Soke Nelson
