I am using the code below to allow people to send mail on my page. It completes the To: field and Subject: field

<BODY>

<FORM>
<INPUT TYPE="button" VALUE="Feedback" onClick="parent.location='mailto:[email protected]?subject=Check out this page !'">
</FORM>

This works fine, but how can I amend this so that I can place a URL in the content area of the e-mail ?
