> Is the ‘forum’ the “forum” I want to remove?

No. It’s a little more complicated than that. In fact, that part you say needs to be hacked, needs to be left completely alone. Really, you are asking for a world of pain by attempting this. It took me hours to write and test the slugs support. Seriously, just rename your forum directory – it’s not worth the hours you will spend.
