"Form": tell people about this website

Does anyone have the code for the little form along the lines of:

1) visitors puts in friends email addresses
2) clicks send
3) website sends message to the email which visitors hace input in form.

I think this would be a good way of promoting one of my sites.

Cheers
Jamie
