That doesn't matter.I HAVE TYPED IN CAPS FOR NEARLY 45 YEARS SON.
Some netiquette for the newbie:
Never type a whole message in caps, whethere its an instant message, a reply to a post in a message board, or in an email. writing a whole message in caps means that one is yelling (unless you do not mean it that way). If you do not mean it to come across that way, make sure you tell people you are not yelling. Remember, people can not tell what mood you are in by just typing something (unless you are using a webcam and microphone of course...). So please please please do not use caps to write messages. Thanks!
