Crawl and copy Google Groups ( forums )

[Elium]

Hello everybody,
I was trying to figure out on how to crawl and download Google Groups ( forums ).
I've read few discussion here about Google authentication,
but after a few hour of test ( ) guess I can't set WebCopy correctly.

I always get on the ERRORS tab this URL https://accounts.google.com/signin/challenge/sl/password with Status Code 302

I found by the capture module Passwd= and Email= parameters (not sure about the many others if are needed), when I test the URI https://accounts.google.com/ServiceLogin#identifier from the form it seems to work, WebCopy brings me on the "second page" when is needed to put the password.

The problem is that always get one error, Status Code 302 on URL https://accounts.google.com/signin/challenge/sl/password 

Does anybody have never figured out on how sign in on Google account?

Thanks a lot for your help,
have a nice day,
Elia
