I have implemented and styled my Mailchimp Subscription form and when I tested it I saw that the 'THANK YOU' after I submitted a test email opt in, was GREEN!!! NOT GOOD!
This does not match my site at all, I looked everywhere to change this and thought I edited the CSS in the editor, but it did not work.
Here is my site, but then only way to see it is to join the mailing list. I don't see a place to upload a screen shot here or I would.
