[Plugin: s2Member® ( Membership w/ PayPal® )] Would like mandatory confirmation email registration

I haven’t researched this completely, but I would like to require people registering at Level 0 (free) to have to confirm their membership with a link delivered to their email, thus ensuring that I have a valid email address for the person.

I am considering MailChimp integration as well; not sure if that could provide confirmation features for registration.

Bottom line is I want people to have to confirm their registrations.

Any thoughts on this?
