Useful Online Utility

Go take a look at this interesting and useful service.
www.changedetection.com offers a "free" website monitoring service.

Let's say you want to know when a certain person's webpage is modified or changed in someway. Instead of manually trying to go look at the site every so often, let changedetection do it for you.

Goto their site, and enter the url of the site you want to monitor. Then enter your email id where you want to be notified.

That's all you have to do. Now, whenever the page that you are monitoring changes, changedetection.com will send you an email notifying you of the change.
