I am doing some research on epinions.com and try to download the webpages. But
I got so many of them, and httrack seems give up after many links. following
is the error I got.How to use #L option?(When do I put it? use it in command
line?)

Too many URLs, giving up..(>100000)
To avoid that: use #L option for more links (example: -#L1000000)
