I need to integrate newsletter singup within contact form 7. As newsletter provider I am using MailChimp.
I found this tutorial http://www.adam-bertrand.com/blog/?p=17
Unfortunately it seems like it points to old version of contact form, I can not find mentioned code to inject integration.
I know that I should add integration code inside controller.php, however I am not php developer, what is more I can not adapt to changes done to new plugin version.
I would be grateful for any help.
