ok, that makes some sense. it can be hard to find resources if you are looking for tutorials, examples or guides rather than specifications... not just for this but in general. the trick imo is to learn not to require those things... which you seem to have managed. but you are right that its a lot easier not to have to work stuff out from the basics. :)
