$userid not found in class_dm_threadpost.php

[Andy]

I'm trying to make it so only the admin has the ability to use all uppercase in a thread title.

Line 183 in the class_dm_threadpost.php file I have added a condtional.

if ($userid != 1)
{
$title = fetch_no_shouting_text($title);
}

It does not work as expected, I suspect the $userid variable is not know in this php file. Do I use a require once to make this work?

Thank you.
