Send Email from HTML page

Something people have asked me to do before.  I didn’t know how to do it, but I’ve found it here:

The form has an action mailto:email@ddress.com?subject=blah blah

And the form submission data is the body text of the email.  In FireFox anyway.  IE seems to add a postdata attachment instead.  But I guess if one of the fields was called “body”, then it would be the message text.

It’s kindof ok.  But ugly in both.  Anyone know how to do this nicely?
