Won’t work with future posts… here’s the update:

With WordPress 2.2 you have the ability to post in the future. This requires wp-cron.php to be called by WordPress in the background. Unfortunately wordpress can’t log itself in! This fix should do, change the function in registered-only.php to look like this:

function carthik_bouncer() {
if ( $_GET[‘check’] != wp_hash(‘187425’) ){
if (substr($_SERVER[‘SCRIPT_NAME’], -12) != “wp-login.php”) {
auth_redirect();
}
}
}
