Does anyone know the name of the Nirvana controller/method combo that lists the thread numbers of a user's unread message wall posts? I thought it was under WallNotificationsExternal or WallExternal, but neither of those have the method I need. I suppose I could sift through wikia/WallNotifications, but I figured I'd post here first.
