Sometimes,if you're looking for question-answer type of thing and especially on
web based bulletin boards, it is simply easier to cut and paste the things you
want to know, than use any web copier like HTTRack.

If you use HTTRack to do this you creat a whole lot of load on the board, but
what you actually gain, the actual information, is very little. Thus you are
using the bandwidth  up to nothing.

Sometimes the brain is more powerful than the muscle (HTTRack).
