I am just of the opinion that you should only ask if you're truly stumped and cannot find a relevant tutorial. I'm fine with helping, but I'm not terribly keen on doing someone's work for them, no programmer is or ever will be. To quote a rather old book, if you give a man a fish he's fed for the day, but if you teach him HOW to fish, he's fed for life. To continue the metaphor, giving Wizzie a fish will teach him nothing of looking through the code or how the engine works. I'd rather give him a pole, line and hook (using search on DHW and experimenting with the code himself) and he find his own fish.
It was just a rant about the value of learning things the old fashioned way, but I'm an old man and it should be taken with a grain of salt
