using sesion_is_registered() depends on a couple things:
1. register_globals is on
2. you are using a super old method of using sessions.
1. if you're relying on register_global to be on that is usually
frowned upon. The best method to do sessions is usually with
$_SESSION, if you're not using an archaic versionn of php.
// start session
session_start()
// set a session var
$_SESSION['var'] = 'a value';
// check session existence
if (isset($_SESSION['var']) ) ...
// unset session var
unset($_SESSION['var']);
2. read http://php.net/session a couple of time's to verify correct
usage. and *do* take not of the "warning" sections.

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!
