SMF like ssi.php
 

I use to run SMF board and having a lot of 3rd party software on in it ( like raid planers, dkp etc... ) I need to add a code to index.php of that code that will check usergroup (all usergroups not just primary one) of currently logged user and if its wron php die.

What kind of solution Vbulletin offers for that.
Checked manuals but about syndication but did not saw anything about it.
