Or do it my way.
Make a folder with the name of the website you gonne send them too ..ex yourdomain.com/gfy
in there you make a index.php page with the following line
<?ph*p
he*ader("Loc*ation:
http://www.gofuckyourself.com");
?>
without the * ..then you can just from everywhere link to yourdomain.com/gfy ... and you're done ... build a counter in it ..and you knwo exactly how much you sent too.
