In emails, blog commenting and discussion groups, you don’t need audio facilities to appear (and sound) like shouting.

How?

Try writing in ALL CAPS, that’s how.

When you write in all capital letters, this is considered by many recipients and readers as if you are shouting.

If all you want is to put emphasis on some parts of your message, use ALL CAPS for those important words only. (Or the other technique is to enclose the *important* words with asterisk like in this sentence.)

ALL CAPS have strong effect. If used in abundance, they have the same effect like shouting – and nagging. They annoy the wits out of the recipients and readers. Your messages lose their effect as they are completely ignored or deleted. Or, in discussion groups, if you repeatedly use ALL CAPS, you run the risk of being banned.

If you type in ALL CAPS because you find it faster and more convenient, consider using all lower case only.

You may not pass your English 101 class when you type in all lower cases, but the practice appears more widely accepted than ALL CAPS. And your message may get across easily.
