I copied one of these blogger sites a long time ago.

Go to the <http://doc40.blogspot.com/> page. On the warning page where it reads
"I understand...", hover the mouse pointer over the "I understand..." box and
right-click the mouse and copy the URL location. That is the URL to paste into
Httrack for the web link to copy. Do not click on the link to open it.


Because on the blog pages there are links that revert back to the content
warning page in Httrack filter out the content warning page with:

-http://doc40.blogspot.com/

and you may need to filter out login with -*login*

That should be it but if you still see the content warning page you will have
to check for other links that go back to the warning page.

You may need to fine tune the Httrack rules to copy the site the way you want
but that should get you started.
