Hello everyone, i am brand new to martial talk. i have a few questions that any help would be greatly appreciated on. first let me explain my situation. my grandmaster recently had his second stroke and its not looking good. four of his black belts(including myself) have come together in an effort to keep the school going however we do not have a 4th Dan among us. if i am not mistaken, without a 4th dan, we can not certify any black belt promotions correct? also, for 2nd, 3rd, and 4th Dan, do we need more than one master to sign off on the promotion? if so, how many do we need? how can i find out how much is the bare minimum we have to pay in order to get ourselves promoted to each of these Dans? a little information about our school... we are out of Miami Florida, we've been running since 1996, i believe our grandmaster is 6th or 7th dan. any help is good, thank you.
