Dear Mr. ``The Doubtfire'',
Since we all check the mailing list in our free time, and since it's a totally voluntary job that we are doing, we try to solve as many problems we can in a short time. Queries that are posted on this mailing list must be precise & related to GNU/Linux. We became irritated with you not because you didn't try google before posting the query, but because what you asked had simply no meaning & seemed totally off-topic. You were simply asking about ``how to change a printer cartridge''. No matter what you actually meant, you query seemed totally baseless and that's what invited so many flames. When asking anything on a mailing list, you should be totally to the point otherwise it can piss people off & then there would be no point blaming people for being ``rude''. I advise you to be careful about that in future. If you follow that, I am sure you'll get the desired solution in most cases.

N.B. In that regard, I'd recommend reading RFC 1855 from http://www.faqs.org
