I haven't gotten through all of this yet, but should be an interesting read. The UKBJJA is essentially the governing body for BJJ in the UK, for those who don't know. Not officially, but it's definitely the closest to a proper governing body (and no IBJJF shenanigans, as the UKBJJA is non-profit, elected board, actually does stuff to try and help the sport, etc).
