Hello
I am trying my first app
It works fine, but Twitter ask for permissions on every Login, instead of transparent login since authorized
Thank you for your help
INDEX FILE

session_start();

echo "<b>SCREEN NAME</b>: " . $_SESSION['TwitterScreenName'] . "<br />";
echo "<b>NAME</b>: " . $_SESSION['TwitterName'] . "<br />";
