Contact Column Headers

There used to be 2 other columns for the all contacts listing. One was "date registered" (or something to that effect) and the other was how they registered (via website or entered by me). Being able to sort the contacts by this listing made it easy for me to check new contacts who signed up for emails via our website. When people do this, we also log it into our parish database. Now I have no idea if people signed up for a newsletter on their own. I checked this list once a week to stay on top of it. It should at least be an option for column header that people can choose or not choose as they need.
