I have just read through the tutorial and it is very good and informative. I have made some comments, but in the main they are very minor points of grammar.Ulrik's hard work, you mean.
I do feel that this task is enormous and as XYP is so feature rich, you might never finish it! From a personal stand point I hope you do as I have already gained a lot from this tutorial - well done!
