~~Why have a ranking system in Aikido? Most other MA hold certain info. at certain ranks and you can't practice that material unless you achieve that rank. But in Aikido we all practice the same things, over and over, nothing is withheld (as far as I can tell) and you're free to ask any question at anytime and get material. Everyone just pracices from exactly where they are--which is all you can do anyway. So...what's the point?
