I am trying to get a google ad code on my site http://www.crystalgamer.com
It is using an Arthemia theme.
I have got the code but I am not sure exactly where to put it
I have looked in the index.php and the header.php and i tried to find the <body text to put it between but I can't find it.
Maybe i am looking in the wrong .php file.
Please can someone help me.
