William,

Thanks for replying.  What you listed appears to limit the forums it searches,
but it's grabbing each message as if it was it's own thread (grabbing all
previous posts in the thread, to boot).  For example, if a thread has 5
messages in it, HTTrack will create 5 separate HTML files (each larger than
the previous)... file 1 has post 1 in it, file 3 have posts 1-3 in it, etc.,
all with the normal forum header/footer details.  This site also has two ways
to view the threads (chronologically or by sub-thread), and it appears it may
be considering that option as an extra iteration to sort through.

How can I force it to place all posts in a single thread into one HTML file
per thread?
Here's a prime example.  The following subforum has about 10 threads, making
it a great test forum.

After downloads hit 20Megs I figured something was up.
