title: Use jQuery to append star to menu item if the linked page's content has changed since last visit
body: <p>I would like to create a similar effect to Apple's Safari 4 Beta Top Sites page -</p>

  <p>when when you view it and a page's content has changed since you last visited, it displays a blue star in the top right hand corner to notify you. </p>
  
  <p>I would like to do the very same, but only within my website and instead of an image I would like to append a '*' or some other character to the menu item's link.</p>
  
  <p>I'm sure you would use the jQuery Cookie Plugin, but my scripting is not that advanced and I do not know how to dynamically change the cookie's content. Have I explained properly? How would I do it?</p>
  
  <p>Many thanks in advance</p>
