(sorry for my bad english)

For searching a new job I need a free of charge and pratic
solution, possibly a web service instead of an application to download
and execute on my PC, for receiving automatic alerts when certain web
pages, specifically the "work for us" pages that I indicate, of some
companies change and contains some specified keywords like "Internet",
"tcp", "network", "informatic", "web"...

These pages must be automatically checked for changes and
correspondances at least 1 time a day.

Thanks for your help.

An excellent descriptive list is here:

Another descriptive list:

Another minor descriptive list:

The best PC application I found is WebSite Watcher.
The second best is Webspector.

This is all!
