Give WWWizzzard a URL to check, and tell it how often.  When it detects a change of status or content^*, you get an email including the changes.  Each one costs a "credit".  You get 60 free credits to start with, and one more every day (to a maximum unused accumulation of 90).  Want more?  Convince me to raise the limit, or that you're willing to pay enough that it's worth my time to collect money.

Sound good to you?  Sign up with the link at the top, and click the link in the confirmation email you will receive.  (There is nothing you can do here before confirming your email!)
