We are adding a Send to a Friend link on our site. I am limited to how I can do this, so no forms - just a simple mailto protocol. Here's the code:
<a href="mailto:?subject=Some kind of subject&body=Hello,%0A%0AI thought you'd be interested in this important information."><img src="/images/email_logo.gif" border="0" /></a>
Remember, the surfer needs to fill in the person from their address book to email this to, themself, we aren't doing that for them.
