[Eagle of Fire]

Standard netiquette is pretty much standard common sense. Not aknowledging it is pretty much like sipping your soup, talking loudly at dinner, making unappropriate sexual or disgusting jokes while some people are not finished eating and similar faux pas.

Which mean that it won't really make a real difference and you won't absolutly get into trouble for it. But it will sure annoy the hell out of those who care, and it's not going to give you a good reputation.

As for netiquette rules, would I really need to give out a link for it? Just fire up your prefered search engine and you should get a few dozains direct links. I know Wikipedia have a nice page about it.
