Bob & Torch,
All caps are considered shouting because they "jump off the page" at you. It is easier to type all in one case (I sometimes type in all lowercase) but it is more difficult to read a message in all caps. Having looked at Navy message traffic for too many years, I can vouch that reading lots of messages in all caps can be a challenge.

Terry, whoever shared the comment with you appears to have done it "off-line", or via a direct e-mail to you. No one was picking on you, just offering a suggestion. You will find that everyone is welcome here, and we enjoy all the posts from each forum participant. Keep on posting and sharing your thoughts with us!

Dave
