Website to monitor another site and email you when the page changes?

[Kelemvor]

I know there are sites like this but I don't know the names of them. Does anyone know of any site that offers a free service here you give it a URL and it checks the page every day and if it sees the page has changed, it send you an email?

These are great for when you are looking for updates for pages that don't have automated email services.

Thanks!

Any ones that don't require a phone number? I put in a number that went to Information and got an email that my info was invalid. WHy the hell do they need my phone number when they have my email and mailing address? I'm on the do not call list for a reason.
