Well, I have some info about the file name, so it's not the point for me.
Also, wget can get the directory, so we can use wildcards after the download, i think.
though wildcards are not supported for HTTP, you can still use -r and -p.
and btw, if this forum works similar to database-driven phpbb, there's no page such as curl. there's showthread.php, and p seems to be the thread index variable, whose contents will be fetched from database when showthread.php is executed.
