Confirm Mailchimp Subscription before WP password is sent

[SteveCox]

Hi, I'm trying to get a membership site up and running with mailchimp integration. Naturally the S2member plugin is the perfect choice however I have one question....

Currently the users signs up to the site and gets a "welcome to the site... here is your paasword" email, then through the mailchimp integration gets another email asking to confirm their subscription to the mailchimp list.

What I would like to do is to only send the "welcome to the site... here is your paasword" email if the user has confirmed their subscription to mailchimp....

Thanks in advance.
Cheers, Steve
