I have debugged this!

In Mailchimp on the API link there’s a record of the API calls. It had an error code:
(250) List_MergeFieldRequired

I took off all my mandatory fields in Mailchimp, and it worked. I assume that the request was chucked out for not fulfilling a mandatory field on my list sign-up form. I can now get S2 Members onto Mailchimp.

Hope this is helpful :)

Now to work out Groups.
