Many people are familiar with the old saying, 'mind your manners.' But what about etiquette for the Internet - or 'netiquette,' as it's called.

For those who use the computer as their prime source of communicating with others, there are a few important guidelines to keep in mind.

First, don't shout. In other words, don't type in all caps.

Second, be civil. Keep in mind the reader can't see all those non-verbal cues that indicate if you're serious - or just kidding.

And think carefully before sending an e-mail. Once you click that button, it's out there and you can't get it back.

Finally, be careful not to click the 'Reply to All' button. You might say something you don't want your boss to read.
