I want to collect information from a user when he's in a web page.

For example I want to have fields on that web page and let the user click a submit button when he's through entering the information.

After that I want that information to be sent to me by e-mail.

I've heard about a utility called CGIMail.

How can I get it? Is it free?

Are there other utilities that would do the same? Freeware if possible.
