I read the info on how to add a hidden field for my sign up location... So, I added the hidden field to my list in Mail Chimp, and then added the appropriate code into the html... as this sign up list is only for a certain location/site.
I tried using embed code as suggested, onto a WP page, but it's not the prettiest and does not retain extra line breaks I added to the html.
It was recommended I use your plug in... BUT...
how to use the plug in, so it includes that version with the hidden field?
Any solution?
