is it possible to have mailchimp integrated with e-newsletter

Hi there,

Just wondering how does e-newsletter subscribe visitors for the newsletters. I do see there is a widget for it but wondering if I could get mailchimp integrated with it.

What I meant, to use the email addresses of all my subscribers via mailchimp for e-newsletters.

Appreciate your answer on this or I will appreciate if you could advise me on the best possible email subscription method using WPMU plugins. I want to use subscription form as popup.

Thanks in advance.
