Yesterday i have seen a new menu in top bar section of my profile named as review. I conclude that it is due completing 500 reputation.
Today when i have clicked on review menu i have seen 1 post present for review. I have reviewed that post and in that page saw there are lots of post present for close and think about the question ask by @Molot "Please review close votes!".
But i think it will be better if their is a notification present in review menu for like, friend request in social networking site. Then post will be easily reviewed by user.
