I have signed up for a newsletter that only asked for my email address. After entering my address into the field then submitting, I was taken to a longer form but the email field was already filled in from the simple form they had on their homepage.

I have a sign-up form on one page but it takes up a lot of room. Is there any way to have the email address transfer from a mini form to the email field of the full form after a use clicks SUBMIT? that way they will be taken to the detailed form to actually complete the sign up
