I'm using "Widgets on Pages" to place your MailChimp Widget on a page... Works fine!
What is the duration of the cookie that's set? Can it be changed? Where?
Also, is it possible to add a redirect so that if the form has been submitted (i.e. the cookie set), you will be redirected to a particular page? Both on submitting as well as upon return to the page with the MailChimp Widget.
That would be *way* cool! (and handy!)
