Re: Hide topics
Here are some more detailed instructions for you:
1) First, create a new forum and call it “Hidden” or something similar.
2) Upload and activate the Hidden Forums plugin.
3) Get the forum id number here: http://yoursiteurl.com/forums?forumlist
For the sake of this example, let’s say the forumid of your new forum you want to hide is #3.
4) Now edit the settings manually at the top of the plugin:
http://svn.automattic.com/bb-plugins/hidden-forums/trunk/hidden-forums.php
Use the settings below, at the end of this post.
5) Reupload your plugin with the new settings, and see if it works!
Hope that helps! 
$hidden_forums=array(3); // hide these forums, list by comma seperated number
$hidden_forums=array(‘keymaster’,’administrator’); // these roles can always see ALL forums regardless
$hidden_forums[3]=array(‘administrator’,’moderator’); // exact formal role name, *not* ability
$hidden_forums=array(1); // these users can always see ALL forums regardless
$hidden_forums=”[H] “; // text, html, css or image to indicate hidden forums/topics, make it =””; if you don’t want any label at all
