I'm trying to grab all pages/threads from a subforum, including attachments and
images.  How can I prevent HT from grabbing pages outside of that specific
subforum?  As it stands right now, the links to parent forums also get crawled
as they always appear somewhere on the page, defeating my original intent.

Here's an example site/subforum I'd like to crawl offline:
