This is a conventional mailto:tag
This mailto tag cannot be grabbed by spam robots !
By replacing your conventional mailto: tag with a command to call a simple javascript code, you can stop spam robots from grabbing your e-mail address from your web site.

The code works by breaking your e-mail address into small parts and then using javascript to rebuild them.

<script language="javascript">
<!--
function spambuster() {
var first = "yourname"
var second= "domainname.net"

location.href="mailto:" + first + "@" + second;

}
//->
</script>
