24 The Core Rules of Netiquette 24 24

25 Rule 1: Remember the Human The golden rule: Do unto others as you'd have others do unto you. Easy to misinterpret meaning of words. Lack of facial expression, gestures and tone of voice to convey meaning. Would you say it to the person's face? 25 25

26 Rule 1: Remember the Human (cont.) When you communicate through cyberspace your words are written Any message you send could be saved or forwarded by its recipient. You don't have to be engaged in criminal activity to want to be careful! You have no control over where it goes. It is unethical to forward a message without asking permission of the originator of the message. Do not make changes to someone else's message and pass it on without making it clear where you have made the changes. would be misrepresentation. Use the BCC -Blind Carbon Copy- function when sending a message to a large group of contacts especially if the recipients of your mail do not know each other

27 Rule 2: Stick to real-life standards of behavior Different standards of behavior BUT not lower than in real life. Be ethical encountering an ethical dilemma in cyberspace, consult the code you follow in real life. If you use shareware, pay for it. encourages more people to write shareware. The few dollars probably won't mean much to you, but they benefit all of cyberspace in the long run. Breaking the law is bad Netiquette

28 Rule 3: Know where you are in cyberspace Netiquette varies from domain to domain. What's perfectly acceptable in one area may be dreadfully rude in another. Important: know where you are! Lurk before you leap take a look around. Spend a while listening to the chat or reading the archives. Get a sense of how the people who are already there act. Then go ahead and participate

29 Rule 4: Respect other people's time and bandwidth Bandwidth is the information-carrying capacity of the wires and channels that connect everyone in cyberspace. Storage capacity of a host system. If you accidentally post the same note to the same newsgroup five times!, you are wasting both time (of the people who check each copy) and bandwidth (by sending repetitive information over the wires and requiring it to be stored somewhere)

30 Rule 4: Respect other people's time and bandwidth(cont.) You are not the center of cyberspace! Don t expect instant responses to all your questions. Don't assume that all readers will agree with your passionate arguments. Ensure your message is worth the time it takes to open it. Before you copy people on your messages, ask yourself whether they really need to know. If the answer is no, don't waste their time. If the answer is maybe, think twice before you hit the send key

31 Rule 5: Make yourself look good online Take advantage of your anonymity. You won't be judged by race, color, weight, age. However, You will be judged by the quality of your writing. spelling and grammar do count. Know what you're talking about and make sense. Pay attention to the content of your writing. Ensure your notes are clear and logical. Be pleasant and polite. Avoid offensive language

32 Rule 6: Share expert knowledge Don't be afraid to share what you know. The strength of cyberspace is in its numbers. The Internet is to share information. If you ask a question and anticipate a lot of answers Share the results If you re an expert, or you've researched a topic that you think would be of interest to others: Write it up and post it. Sharing your knowledge is fun. And it makes the world a better place

33 Rule 7: Help keep flame wars under control Flaming is what people do when they express a strongly held opinion without holding back any emotion. Netiquette does not forbid flaming! Flaming is a long-standing network tradition (and Netiquette never messes with tradition!). Flames can be lots of fun, both to write and to read! The recipients of flames sometimes deserve the heat! Netiquette does forbid the perpetuation of flame wars Can dominate the tone and destroy the camaraderie of a discussion group

34 Rule 8: Respect other people's privacy You d never snoop through your colleagues' desk drawers, so naturally you wouldn't read their either. Failing to respect other people's privacy is not just bad Netiquette! It could also cost you your job! 34 34

35 Rule 9: Don't abuse your power Some people in cyberspace have more power than others! experts in every office, and system administrators. Knowing more than others, or having more power than they do, does not give you the right to take advantage of them. For example, sysadmins should never read private

36 Rule 10: Be forgiving of other people s mistakes Everyone was a newbie once. When someone makes a mistake be kind about it. If it's a minor error, you may not need to say anything. Even if you feel strongly about it, think twice before reacting. Having good manners doesn't give you license to correct everyone else. If you inform someone of a mistake: point it out politely preferably by private rather than in public
