Flaming is starting online fights through angry words. To prevent flame wars, avoid spam and be polite. Netiquette means having good manners online, like you would in person. Emoticons like ;-) and ;_) are used to convey emotions. The basic rule of netiquette is to remember you're talking to people, not computers. If a site makes you uncomfortable, stop and log out. Public emails can be viewed by anyone, while private emails are only viewable by the recipient. Using all capital letters looks like shouting. To stay safe online, don't share personal details like your address, phone number, school, or parents' credit card. Only share information that can't be used to identify you.
