Web Secretary - Web page monitoring software with highlighting

 A visual Web page monitoring software. However, it goes
 beyond the normal functionalities offered by such software. Not only
 does it detect changes based on content analysis (instead of date/time
 stamp or simple textual comparison), it will email the changed page to
 you with the new content highlighted.
