I will glad to help answer:
1. The "Add Comments" feature: After you submit your comment, it then is placed in a queue where the manager of the Developer Zone reviews the comments. If approved, the comment then will appear on the bottom as part of the document it is related to. One of the reasons for the approval process is to make sure that support questions are properly routed and don't go unanswered. The main purpose, however, is to receive our customers feedback on the technical content we offer them.
2. Thank you for the notification about "Review Guidelines" link being broken. I will work to restore it.
Thank you for your interest, inquisition and notification.
