From questions appearing in the forums, it looks like classes have started up again, and some people are looking for help with their homework assignments and/or projects. (Or, some people are looking to get "the internet" to do their homework for them.)
I've always found this a bit ambiguous. Practices considered "cheating" in school are "preferred" in industry (find code, rather than writing it from scratch.) But equally, you don't learn what you're supposed to be learning if you get correct code from someone on the net without doing any struggling on your own. And some of the questions look like the person didn't bother to even go to the class...
So it's up to you, but if you see a particularly contrived question from a newbie, you may want to temper your response to something more "educational" than an exact answer.
"Nicely", of course. This isn't AVRFreaks... (or don't respond at all.)
