Yes, httrack will never follow forms (forms with POST or 
GET data), for two main reasons:

- complex to handle (multiple elements inside a form 
object, and sometimes "non guessable" elements such as 
lists, checkboxes, or text inputs)

- dangerous to handle (unlike regular links, "form" links 
can have non-invariant actions, such as "delete a message" 
or "send a mail" - imagine you download a complete site 
following all "delete this message" or "reply to this 
message" links..)
