OK! :)
Mira, al principio de las paginas tengo lo siguiente :)
<?php

Este es un pekeño Script para el menu superior donde hay pestañas para acceder a todas las opciones de esta :)
Despues escribo el menu dependiendo de si el usuario esta registrado o no, y
del tipo de usuario que sea, aki tienes el codigo:
<?php
if (!isset($tipo) OR !isset($id) OR $user == "")
//El alumno no ha pasado todavia por la seccion de registro
{
//header(Location: "../html/registro.php");
