I am using s2member with mailchimp. When a user registers he/she is sent a mail from mailchimp. When the user clicks the confirmation link in the mail they are addded to the mailchimp's list. What I want to accomplish is
That after registering on the wordpress website, Until a user has been added to the mailchimp list (by clicking the link in the mail from mailchimp) , they should not be able to log in to the wordpress account.
