Is there any script for invite a friend feature???

Nope

fair enough!

I was wondering if there is yet. It's been 1 year and I just wanted to know if it's been added or not

Place this script in your homepage message or a widget:

Code:

<script LANGUAGE="Javascript">
<!-- Begin

//script by Trånn: http://come.to/tronds
//Submitted to Javascript Kit (http://javascriptkit.com)
//Visit http://javascriptkit.com for this script

var initialsubj="Hay buddy, take a look at this"
var initialmsg="Hi:\n You may want to check out this site: "+window.location
var good;
function checkEmailAddress(field) {

var goodEmail = field.value.match(/\b(^(\S+@).+((\.com)|(\.net)|(\.edu)|(\.mil)|(\.gov)|(\.org)|(\.info)|(\.sex)|(\.biz)|(\.aero)|(\.coop)|(\.museum)|(\.name)|(\.pro)|(\..{2,2}))$)\b/gi);
if (goodEmail) {
good = true;
}
else {
alert('Please enter a valid address.');
field.focus();
field.select();
good = false;
  }
}
u = window.location;
function mailThisUrl() {
good = false
checkEmailAddress(document.eMailer.email);
if (good) {

http://window.location = "mailto:"+document.eMailer.email.value+"?subject="+initialsubj+"&body="+document.title+" "+u;
window.location = "mailto:"+document.eMailer.email.value+"?subject="+initialsubj+"&body="+initialmsg
  }
}
//  End -->
</script>


<form name="eMailer">
Tell a friend:
<input type="text" name="email" size="26" value="    Enter Address Here" onFocus="this.value=''" onMouseOver="window.status='Enter email address here and tell a friend about this site...'; return true" onMouseOut="window.status='';return true">
<br />
<input type="button" value="Send this URL" onMouseOver="window.status='Click to send an email (with this page address) to a friend! Enter email address above...'; return true" onMouseOut="window.status='';return true" onClick="mailThisUrl();">
</form>
