BBSs and Chat Rooms are basically the same as a publicly posted Email message. For netiquette issues on Chat Rooms and BBSs, you can jump to the Group section of the Guide. Be Polite Being polite doesn't just include what you say, but how you say it, and to who. If you use humor or sarcasm in your correspondence, be sure the recipient is going to appreciate your sense of humor. If you're having a bad day, it'll probably show in your message.
Email is about convenience.
Keep your messages brief and to the point. If you write long messages that drift from one subject to the next, your reader's attention will drift as well. Also, take the time to delete long header text when you're forwarding or replying to an Email. Use acronyms and emoticons to give your messages some character. The subject line is the only label you have to identify each of the messages in your mailbox with.
