I was wondering if there are any monitoring sites which would notify me when another site updates a page? Just an e-mail to me saying "SoccerBritishColumbia.not" has just updated their page. (Not a real URL)
What you need is a service with something like a web spider that grabs server headers and looks at the last modified statement for any changes. Another way to do it would be to spider the html code, keep a record in a database, and then make to checks to see if there were changes.
Do a search on google for web site monitoring. Most of the services I think are geared toward alerting you if your site goes down etc. but you might find something that fits your needs.
