86 if you point out to me specific sources that can t be used and why I don t use them I considered black belt magazine a reliable source I now know what a passing mention is I went over to RS once as suggested and it was such a long read and confusing I said forget it When I put up a post and you or someone says its not reliable check to see if I put it back up The black belt magazine that you said was copyrighted I showed that link to an admin and they didn t say it was a bad link First I heard about it Did you see me put it back up nope It is only to show that Ron Duncan was a noteworthy martial artist Past that he s been dead for a few years The website is run by his son I believe so it may not necessarily be self published
