How are people doing this?

How do people (I guess its tagging) celebrities or even just people in their own wall posts, and it shows up on whoever or whatever the tags wall is? I am not sure if I am explaining this right. I have seen posts like this omg did you see Justin Bieber doing coke, or something like that. Then they will put a list of popular "walls" under this post 4,5,6 or more and that post goes to the walls that they made the the list of. Those popular wall lists are also blue and clickable. I have even seen people do it that are not even spamming or anything. Just mention someone in a post thats on FB and is blue and clickable. But when I try it they are not blue and clickable and don't go to the walls in the list. Can anyone help, if you understand what I am talking about? Thanks

use @ before the name of the page

They tag the pages As Stzzzz said, with @ in front of the page name

This method will die soon Some pages has started disabling the walls

You guys are the best! Thank you so much! I "thought" I had tried everything, and it was about to drive me crazy! And believe me, with the way things have been going for me lately, it would have been a short trip! I even thought maybe there was a script for it or something, lol You have at the very least saved one person from going to the nut house! BHW Rocks!
