> Is there a link to the Tutorial elsewhere that I've missed, and if not, could you put one somewhere on the AGL feature page?

No, and unfortunately, no. The best I can suggest is that you bookmark it. As far as I know, you, Stephen, Dave, and possibly GreenJeanz are working on games right now. When you guys get to the implementation/testing phase, that'll be about as much as I can handle. After two or three of you either finish or decide not to do it, I'll probably post a link on the AGL page, but for now I don't want to publicize it too much.
