I purchased a copy of your book several months ago. And I find that I use it quite a bit. It is very helpful for someone of my rank (mid kyu's) who is trying to learn the material, and to be able to "remember" the things that we learn in class. Sometimes seeing a description and picture of what our Sensei has shown us really helps to make it all come together when practicing at home.
Anyway, I guess the point is that I really like your book. I find it a great resource, and would like to thank you for the effort you put in to making a quality resource for us (I know of at least two other students in our dojo who also have a copy). Also, I think it's great that you'll make additional copies available for other students.
