Be careful with:
- capitalizing whole words: use capitals only to highlight an important point or to distinguish a title or heading. You might use *asterisks* around a word to make a stronger point. Capitalizing whole words that are not titles is generally seen as SHOUTING.
- using sarcasm and humor: Without face-to-face communications your joke may be viewed as criticism. "Emoticons" (tiny pictures that are meant to be looked at with your head tilted to the left) can be used to put a personal "face" on your messages. See "Smileys for Your E-mail" for examples.
- forwarding someone else's e-mail or bulletin board postings without permission. It’s considered extremely rude.
