how can user subscribe to my website

[Keith Miller]

I would like users to be able to subscribe to my website
and be notified automatically when I have change the
content on any page. How can this be done

You need a form to collect registration data stored in a database
which is the easy part. How you do notifications would depend on
how you determine content has changed. In any event, you'll have
to hire this out if it is a must-have as this objective is not a copy
and paste script.
