It goes I will post a picture of snsd and the first someone ranks the members in that picture and posts another picture of them. and then that second someone rank the picture that the 1st someone posted. GOT IT. you can also just say a song or somenthing like: Oh!, Star golden bell (but all members have to be there), 2nd japan tour..... if you say somenthing like that you don't have to post a picture but you still can if you want or you can add a video
