I want to download this forum, that has two same forms 
(interfaces)

<http://mistral.dkm.cz/phorum/read.php?f=2>

<http://portal.dkm.cz/phorum/list.php?f=2>

it is phorum.org board

Is it possible, I tried it, but each replies has own page 
although it is sufficient to download only one page with 
all thread with all replies (there are cca 350.000 replies)?
How can I manage it to download only these "summary pages" 
belong to board (with whole thread with all replies) and 
nothing other i.e. exclude  it(i.e. without individual 
peges with only one reply, without pages that not part of 
board but another content of web server ?
