I need to use the censorship system.
I had achieved it before one year ago but I forget the changes.

It doen't need to recode all the function. Only the part of character replacement. I remember that it was a simple change to the function.

Well,
I have add the following code to functions_newpost.php

PHP Code:

  // Censorship Warning
  $iwarncens = fetch_censored_text($post['message']);
            if ($iwarncens != $post['message'])
            {
            $dataman->error('iwarn');
            } 


...and when the $post['message'] it is not the same with primary text, this code appears an error message.
The censorship system can change the $post['message']. If the cens system doesn't change the $post['message'] the error doesn't appear.
So, I want to do an as far as possible simple change to the text.. not the replacement of all characters.

The code which I have add, works normally when the cens system change the text...

Thanks and sorry for my bad english..
