My friends at Knownow have been hard at work on the eLerts toolbar and it is now available for free download. eLerts runs inside of IE 5.5 and 6.0 and monitors a set of RSS feeds for changes. When a change is detected an alert is displayed, and the headline is available with a single click. You can see how this works by watching the Flash tutorial.
