The Internet has opened up a whole new online world for us to meet, chat and go where we have never been before.
But just as in face to face communication, there are some rules of behavior that should be followed when you are online. 小题1: Imagine how you’d feel if you were in the other person’s shoes.
For anything you’ re about to send: ask yourself, “Would I say this to the person’s face?” if the answer is no, rewrite and reread. 小题2:
If someone in the chat room is rude to you, your instinct（本能）is to fire back in the same manner. But try not to do so. 小题3: If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.
小题4: Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you permission to correct everyone else. 小题5: At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.
