configuring email sent after registration

Hi,
I want to know how to configure the email sent to a new registration. Right now, it's just user name and password and the subject says [] Your username and password.
blech.
I'm not sure if this is controlled by mailchimp (the responder I am working with) or s2 member.
Thank you.
Kelly
