If I were thinking of taking up aikido and were to receive a handout like the one proposed by Riggs Sensei, I'm afraid that I might reconsider my quest. I would find the length and tone of the handout to be too negative and, in fact, intimidating, especially from an art that purports to encourage (and even require) a positive mental attitude.
I would prefer something a lot simpler, like this (I found it by Googling "How to choose a martial arts school"): http://www.ccmagazine.org/edit/staff/vito13.htm
If one feels strongly about it, at a couple of places in the article a note could be placed that refers the prospective student to a website with additional information, should the student be interested. Where the author refers to the existence of fraudulent instructors, the reference could be to the Furyu article that has already been mentioned, at http://www.furyu.com/archives/issue9/realor.html
