I am using the MailChimp WordPress plugin so that user's can sign up to a MailChimp mailing list. I want the signups to go into a specific group in my list. The plugin doesn't appear to work correctly with mailing list groups.
Can I just dive into the plugin code and add a hidden field to force the users into a certain list?
I tried digging around in there and it looks like the group is determined from an input called "interests". I have tried sending the form with a hidden field with this name having the value of the name of the group I want to use, like this:
<input type="hidden" name="interests" value="Group Name" />
But this does not work. Digging around on Google doesn't seem to offer much help either, as there only appears to be other confused users or not much interest in this particular aspect of the plugin.
How can I do this?
