[Plugin: Theme My Login] role of new registrations, and extra fields

Hi,

with what role are users registered? Is it possible to set the role, or to give a choice of couple of roles during registration?

I apologize if asking too many questions on single thread, but I also would like to know how to add extra fields to registration form.

Thank you
