Never use rules before and a bit lost there... here is what I'm trying to do. It may sounds a bit strange, but...

Drupal 7

I have two Webforms. let call it form1 and form2. Webform Rules module installed.

form1 is located on front page with two fields [name] and [email] .

form2 is a big form.

when submitting form1 the data transferred to form2, so the form2 has the [name] and [email] pre-filled. Data from form1 saved.... now, when user submits form2 we will have two different submissions from form1 and from form2 with the same [name] and [email]
