Is there a solution for the task to display the user agent string near each comment on the frontend (or maybe backend) if the admin is logged in? Or can I use the user agent string in my templates? How?
I found this: http://codex.wordpress.org/Function_Reference/get_comment#Example but where do I put this? Do I have to make a callback function for wp_list_comment http://codex.wordpress.org/Template_Tags/wp_list_comments ?
