Membership plugin registration form to include Name field

How can we extend the Membership registration form to include additional field like first name, and/or last name, or any additional field?

I don’t find the Membership plugin have a broadcast newsletter functionality. Can this be added so we don’t have to rely on another plugin like e-Newsletter.

Or please give me some tips on how to integrate Membership subscriptions and e-Newsletter groups.

Thank you,

Ben.
