INTERNET EXPLORER—The setting is generally located under Edit>Preferences>Browser Display, or Tools>Internet (path may vary a bit depending on your browser version and whether you have a Mac ot a PC). Look for the “Home Page,” section, then replace the existing URL by highlighting it and deleting, then typing (or copy & paste): http://corp.sover.net/start/index.shtml in the text box.
Alternatively, when you are on the page you want to use as your browser’s homepage, navigate to the “Home page” setting as above, and click the “Use Current” button. The URL of the page you're on should display in the URL field—Click ‘Save’ or ‘OK.’
