I've setup RSS feeds for the different categories of Classified Ads for our website. Users can add those feeds to their Google homepages, of course, so all of that is good. What I'd like to do, though, is have the order that the ads are displayed in change each time the person visits their page/otherwise refreshes that feed. It's very beneficial to us to have the ads pop up in a random order each time, otherwise people are seeing the same few ads each time they hit their homepage. For reference, here is the main feed for all our classifieds: http://adkpennysaver.com/rss/rssfeed.php Thanks!
