Best wishes 

Ian, I am sorry to see this sad state of affairs. I noticed your first revert on karate when I got home from the karate dojo last night and considered dropping you a line about the extent of grappling in karate from my own experience. I was however quite exhausted from doing a lot of grappling and picking myself up off the floor numerous times. In my style, Shotokan, the philosophy is to take out an opponent with one blow (ippon) so as to be ready for any others, but we still train in grappling and escapes quite a lot. The movements in any kata can be interpreted in many ways, from the obvious to very complex applications from apparently simple movements. There is no way of knowing if the ancient masters who composed the classic katas had these in mind.

I hope this block will soon be lifted as you are an excellent editor and I urge any admins reviewing this to do so.
