Hi Mo, No, sorry, there is no filtering mechanism. It's not just times_contacted. You will also get notifications when somebody's gtalk status changes etc. This notifications are only intended to serve as a ping - basically telling observers that something changed. You cannot use the notifications themselves to drive the application logic.
