Hello Npongar.
Go to the webpage you want to save, then go to Favorites, and add to favorites, in the dialog box that appears check the Make Available offline tick. and then click on Customize.
Follow the wizard until you get to "How would you like to synchronize this page" there you can select "Create a new Schedule" and set it up however you want. IE will automatically sycnhornize the web page at the time yu specify. provided you are connected to the internet at that time. You don't necessarily have to have Internet Explorer open, just be online for it to work.
Hope this helps.
