The 'My Comments' tab on the Problems Page provides a convenient way of viewing replies on problems you have commented on in the past. The 'My Comments' tab shows a list of problems you have commented on, and all the comments on those problems. The problems are ordered such that the problems that have been most recently commented on appear first. This means you can regularly read the list to view new comments on problems you have previously commented on. Your own comments are highlighted, and a colour bar separates the comments of one problem from another.
