[ Closed ] Category name in Thread/Post page?

EDIT:
Problem solved, i have extend the sql queries in: viewforum.php, viewtopic.php, post.php, edit.php & delete.php, placed a new own "cat_head()" in functions.php and changed $main_elements[forum_main_title] to call my function

Hi,

i would like to display the category _name_ in the "thread" and "post" pages (over div#brd-crumbs-top), like in the "Index" Page (in div.main-head > h2.hn). Thus everyone will see in which category he is situated.

How can i do this?

Thank you very much for your help,
Punner

ps. sorry for my english
