if you point out to me specific sources that cant be used and why I dont 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 didnt 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 hes been dead for a few years  The website is run by his son I believe so it may not necessarily be self published
