Multisite “Skip Confirmation Email” Log Out Problem

Update: I’ve got it working now! It still shows a text box that says the User email must be confirmed, but it DOES create the user regardless of that information. Here is the code I have used:

function your_disable_activation( $user, $user_email, $key, $meta="" ) {
// Activate the user
$user_id = wpmu_activate_signup( $key );

wp_redirect( /*redirect to */ site_url() );
return false;
}
add_filter( 'wpmu_signup_user_notification', 'your_disable_activation', 10, 4 );
