Wathapa.com is a simple website tracking tool. If you need to be informed, when any website changes, simply register on Wathapa.com, enter any web page address and start watching this URL. You can even select level of changes, when you want to be informed. You can receive alert email when any word or link changes on target web page. Or you need to be alerted only if there are significant changes, like complete website redesign, or hacked site? No problem, you can set up both cases.
