If this forum and all its sub forums - Help on code please

[VirtueTech]

Hello,

In forumdisplay.php

I have this

PHP Code:

  if ($foruminfo[forumid]=="181" AND $foruminfo['usergroupid']==96) 


1. How do I say if forumid = 182 and all its sub forums?
2. And How do I say if the user who posted the thread is in usergroup 96?

I can't use $bbuserinfo['usergroupid']==96 because it doesn't give the user of the thread starter. It just checks to see if the user viewing the forumdisplay.php is in usergroup=96.

I want to display something is the user who started the thread is in usergroup 96.

Any help you may have to either question is appreciated.
