Been in touch with Timo for some feature extension to PSN about a year ago, and since I worked and needed it for a customer, he kindly let me try it out before actually buying it. 100% kind and helpful support, plus the plugin is feature-packed and easy to follow when something (as a mistake I made in a rule) goes wrong and e-mails don't get sent. Sorry, but this is a no-brainer, and I will buy it again if I need some fancy notifications :).
