It's very hard to do this well. Consider: you grab a page from a site. You spend one hour reading it (there's a lot of text) and then click on a link it provides to a different site. You start reading that new page. Now consider: you grab a page from a site. You spend 5 seconds glancing at it and then get back to your "real" work. An hour later you go to another site and spend another 5 seconds skimming the resulting page. Finally, consider: you download a page from a site. You spend 5 seconds glancing at it and then get back to your "real" work. An hour later you go to another site and spend another 5 seconds skimming the resulting page. What you haven't realised is that while the first page was open, it was using a javascript applet to update information on the page every few seconds. In each case, how long have you spent "on the Internet", and how does a machine determine the difference? Chris
