Am I to understand that for forums that you set to 'Forum is Open' = No, you don't want the thread list appearing? Or would this be only in this specific instance, where 'Forum is Open' = No on other forums would behave as they do now.

If I'm correct in the former, then this is what you want:
Edit the template called 'FORUMDISPLAY', find:

PHP Code:

<if condition="$show['threadslist']">
<!-- threads list  -->

<!-- controls above thread list -->
<table cellpadding="0" cellspacing="0" border="0" width="100%" 


above add:

PHP Code:

<if condition="$show['newthreadlink']"> 


find, near the bottom:

PHP Code:

<!-- forum rules & forum jump -->
<table cellpadding="0" cellspacing="0" border="0" width="100%" align="center"> 


and above add:

PHP Code:

</if> 


save template. From then on forums that are closed don't show the thread list.
