WwWatchdog

WwWatchdog will monitor your web pages for any html changes (for answers on the forums, text changes you need to track - page title, javascript injections, everything you can specify by regexp pattern). You just specify what a web page you monitor, for what html changes. This utility will get html from your webpages, apply the pattern you specified, and will alert you if count of entries you specified is changed.
Let's say you check webpage title, using regular expression "title>.*MyWeb.*Let me know if I can make this application better, or if you'd like me to implement your requirements.
