Automated Email ( or log file )

[Zak]

First, I hope I'm posting in the right place. This is a JavaScript question. With that said, here's my problem... I want to put a place on my website that users can put in there email address to subscribe to my newsletter. After the user submits there email, how can I log them? I was thinking of having it email me every time but I could figure that one out. Another option I was considering is a log file. But how do you do file I/O in JavaScript?

Thanks in advance...

For this you will need some server side stuff; a servlet, a php script, a perl
script...that is invoked via the http protocol from your web page.

Remember, the javascript is running on the clients computer and the
code at that place can hardly contact your computer, unless your
computer is the server.

Thanks... I know this isn't a Java question but... how could I find out if my web host supports Perl?
