note when you add email, it should go to this new page (like current site)

https://www.miusa.org/newsletter/signup?email=

There are 2 Mailchimp lists here. See checkboxes..?

Note that we want user email to pass through to 2nd page. Also, this (note new layout in ticket 1364) page should show Global Impact E-News checked as well: 
https://dev.miusa.org/international-disability-rights-advocacy/ (see how we re-labeled the name, indicated 2nd newsletter)
