Don't diss PHP I'm such a PHP gal! AJAX basically lets you do some nifty server-side things without refreshing the page. Want a quick example? Make a post on DaniWeb and then hit the Edit This Post button for a demo of what AJAX can do. You might also notice that when you use the Quick Reply form around here, your post automatically appears in the thread without the page being refreshed. For another example of AJAX, go into your Control Panel and click on the Send New PM link. Begin to enter my username, "cscgal", and you'll notice that a drop down list will appear of usernames to select from.
