1) session_start() is not really required on any other pages beside the
index.php because session_register take care of that for you.
2) It should work when you try session_register() on the index.php, use a
makeup name, like session_register("user") then assign the data to it, like
$user[username] = "whatever" & $user['password'] = "passwhatever". This is
a simplier way and it does work.
