I wouldn't worry about Fuku, Shidoin, Sensei..... If you're committed (and who among us that have trained for awhile shouldn't be
) the ranks and titles will take care of themselves. For now, and then, train hard.
Besides, by the time you're ready, who knows what the requirements will be. I know I had particular troubles with the "randori against mounted samurai with uzi's" part of my test ;-).
P.S. If you end up at Aikido of Park Slope say hi to Hal for me. I got the opportunity to train with him in Bermuda and had a great time.
