When your stuff is too old to use but too good to trash, call the Stuff Exchange. The volunteers manning the hotline and Web site will see that your gently used items get a good home, either with a school, nonprofit organization or individual in need. If you're with one of those good causes that needs old computers, furniture or business equipment, check the Exchange to see what's available; if you have stuff to pass on for posterity, e-mail your listing to the Web site.
