Pretty nice.. I can imagine how difficult is to write a tutorial. I would like to make one, I started one once in Flash teaching about 3D in graal, but I couldnt say everything I wanted to, in English. Also I wrote alot of graal tutorials in portuguese to friends. Maybe it would be not so difficult when we do in our first language, anyway. I read it all, and Its pretty nice.. The gui script you could use timeout once, and showstats could be used in other better position. Dont worry about criticize, I think everybody will understand the grammar.. Noone create graal tutorials.. Stefan made almost all actual tutorials, so you made a pretty and great work.
A simple idea, dont use .txt, maybe the tutorials could be in html.. or help format.
Great job
