i am going to write a tutorial too. but it will have a different approach than yours and IMHO 2 tutorials are better than one ...
If either of you (both?) want your tutorials on JGF, drop me an email at ceo @ grexengine.com and I'll sort out an editor for you. Kev's building up a bit of a monopoly on JGF tutorials at the moment
so TB please go for it!
(role of editor: correct your spelling mistakes, provide feedback + corrections on bits that are hard to understand, and any grammatical errors, provide suggestions on extra paragraphs to add, or bits to explain in more detail, sanity check that your code snippets compile + execute, etc)
