I've just read this whole thread and enjoyed it quite a bit. Can see some important names and posters from our small forum too.
Despite the sidetracks and Trollbasher's unusual language (what does "butt polisher" actually mean... sounds a bit crass), I think there is quite a bit of information here. I'd like to contribute with a few extra points, please correct me if I am wrong.
I'd like to mention Isao Obata's group: Zen Nihon Gakusei Karate-do Renmei, they separated during the chaotic period after the creation of the JKA. I'd also like to add that Sodo Kawanabe who was head instructor at the Shotokan dojo (Shotokai Hombu) during a short period in the 50's (I think 56 to 58) also separated and established a group initially called Shotokai Kawanabe and now is called Kenjirio Kawanabe Karate-do which is unlike what people call Shotokan and also quite different from what people normally consider Shotokai.
Kind regards
Mogens Gallardo
