question: if you have a legit user acct and password for a site (access to all the content), is it ok to use the program to rip it all? i dont see why not. i think that is what the op is asking (more of a how do i set up the program to do this, not a help me crack this website).
there should be settings for the program for pw required sites. ihavent used the prog in ages so i cant say of the top of my head. and if you are indeed trying to break into the sites, i am of no help (and you are barking up the wrong tree)
