I am the super admin on my own site. I am running WP 3.4.2 with the up-to-date Auto Chimp plugin. Every time I create a new user, I get 2 emails (a few mins apart) asking me to confirm my subscription to the mailing list.
They are sent to the address that I used when I set up the MailChimp account, not the email address of the new users (I am not trying to sign up these users for the mailing list, just create a new user).
Anybody have any idea what is going on?
