is there a current list of bjj black belts and their lineage? i checked bjj.org but that seems antiquated and i couldn't find links to any lists. i also looked at onthemat but all i came up to was a tutorial for a system wherein you can sign up and list your own rank -- however, i couldn't find the actual database itself. is there anything out there that's considered a legitimate record of who got their bb, and from whom? seems like i could go onto onthemat, sign up, and click the tab that says "black belt", but clearly that's bullshit. thanks!
