We expect other drivers to observe the rules of the road and the same is true as we travel through cyberspace. To add humor and personality to your messages, use smileys , also known as emoticons , expressions you create from the characters on your keyboard.
Some people pay for Internet access by the hour.
The longer it takes to read your messages, the more it may cost them. This is true whether you post messages to a newsgroup or a mailing list. Remember that anything you post to a newsgroup or type into a chat session is a public comment. You never know who's reading it, or who may copy it and spread it around. When posting a message to a public bulletin board, forum, or newsgroup, stick to the topic.
