Can i add put this code in a plugin I currently have the code like this in ./includes/functions_forumdisplay.php.
and which location should i use?

and if it is not possible in this file is it possible in ./forumsdipslay.php?

You should have posted this question in the same thread as the rest of the conversation on this, otherwise you risk getting the wrong answer. It's only because I have read the other thread that I understand what you actually want to do.

If you look in functions_forumdisplay you will see you code is part of a function called 'process_thread_array' and that function has a hook at the very end called 'threadbit_process'.

ok weill do and i am sorry for double posting as well

so it's i can use threadbit_process then... thanks mate..
