I downloaded the Constant Contact widget for my wordpress page. It is meant to be a sidebar newsletter subscribe form. This issue I am having is that it is asking for a "unique form ID code." It says you can find it by setting up "your site visitor sign up form in Constant Contact (Contacts > Site Visitor Signup)."
My question is, where do I do this? I can't find any "Contacts" section that I can set this up in. Can someone point me in the right direction?
