No, I do not have this feature working yet. Below are the steps and screenshots showing what I've done:
Create a forward to a friend (type) marketing page, live:

Adding the marketing page to the Content Settings > Forward to a Friend
Content assist editor > static content > marketing page > forward to a friend > fullpageurl

Content assit > static content > marketing page > forward to a friend > fullpageurl

Created a test email and added the Forward to a Friend link in the footer under the address

sent the email to myself

after I click the forward to a friend link, it opens the page in a browser (I don't why i'ts duplicating the email address; I only typed in the first name and email)

Once I hit the submit button, the page redirects to our website, which is how I set it up

On the insights tab of the forward to a friend marketing page, it shows the form submission

The problem is, I never receive the forwarded email, which I sent my gmail account.
