There's a good chance that you use Microsoft Windows on your computer system. If that is the case, you might be interested in checking out the WindowsTips website, located here:
If you like what you see at the site, you can also sign up for the free weekly WindowsTips newsletter. (A sign-up form is visible at the right side of any page on the site.) I've been publishing the newsletter for several years, but recently (within the past month) appointed my son, Eric, as editor of that publication.
Anyway, check it out. You might learn a thing or two!
