Hi Wes! I believe the easiest (only?) way to do this is to go to the top of the screen when logged in, where your username/icon is. Just to the left of that, there's a "bell" icon, if you click on that you should be able to see a list of people who responded to you. If you click on any of them, it should take you directly to the comment in the thread it was made. Not sure how far back the list goes, but certainly enough to capture many of those notifications.
