Have you ever wanted to know when any particular website is updated? For example, a website that have their registration closed but will have it open again soon, but it doesn’t provide any service that will get you notified when the registration is open again? Or just a dead blog, that you doesn’t want to subscribe to its feed but just wanted to know when it’s updated.

All these can be done by using Notifyr.org – a service that will send you emails when the web page you are monitoring has updated just in 3 simple steps. Create notifyr, wait & relax, get notified. No registration required in order to create a new notifyr. After you’ve creat a notifyr, the web page you wanted to monitor will be checked every 5 minutes for updates – in which I think will be a mess if the service gets too popular (imagine how much work the server have to do every single hour).
