Netiquettes implies to the rules of good behavior in Internet Communication. The only rule that you have to keep in mind is that you have to be considerate with people, even if you haven't met them ever in your life. Advertising in a newsgroup through email is a fairly common faux pas. These unsolicited ads would create enormous clutter if they weren't so strongly discouraged (their senders may be effectively ostracized if users choose to block out messages from offenders). A website is the most appropriate place to advertise because those who are interested can come to you. Typing your comments completely in capital letters ("shouting") is another Internet taboo. Experienced Internet user recommend that people who are unsure of their grasp of netiquette observe the communications of others before leaping in, a practice known as "lurking".
