One of the challenges I have as a SharePoint solution architect is tracking notifications and reminders that go out of Nintex to various users. In some cases users may say, I never saw that email, I was not reminded, ect, ect. One of our helpful tools we have for this is to create Bamboo web parts with a list of tasks for each person. This works somewhat, but it would really be nice to be able to see if a notification or reminder went out. Also, might be good to see these "logs" for debugging purposes also.
