Drupal subscriptions.module: Exclude (current) user from notifications about own changes via HOOK

With the following little HOOK snippet you can exclude users from receiving notifications about own changes in the subscriptions.module:

/**
* Implements HOOK_subscriptions_queue_alter.
*/
function MYMODULE_subscriptions_queue_alter(&$event){
global $user;
if(!empty($user)){
// Prevent users from receiving notifications about own changes.
$event['noqueue_uids'] = array($user->uid);
}
}
?>
