Mail Chimp not integrating

HI everyone, i have spent hours researching this. Have read alot of the forums and posts and have followed everything to the tee as it were. I am just running the standard version of S2. My Api key and List ID is correct and I have also checked the Historical API calls LOG.

Firstly i am still in the testing phase so i added a new user through WP and gave this person role – S2Member Level One. And i also check boxed so they receive a confirmation email from MailChimp. The person clicked on the confirmation email etc
Now under the Historical API calls of the day, just above Mailchimp states – Authorized Applications ( you have no applications authorized as yet ) however the list of API calls indicates 2 calls have been made

so this newly created user i created should they show in the list of subscribers in Mailchimp.
How can i see that newly created users and also subscribers to my site are actually on the mailing list so to speak on Mailchimp

Thank you
