FYI - 

1) I left both 'automatic' activations & creations

    1a) along with the activation letter

2) I removed all 'checks' relative to requests and invitations

     including the relevant email(s)

- A new user can register themselves

  - email verification is sent

  - profile activated email is sent

BUT BUT BUT

I want both:

1) Request Invitation

    - an admin needs to approve the request

      and

2) Existing Users to be able to send invitations

   * I assume that this still requires 'activation' by an admin

Please help me with the proper configuration to accomplish my goals.

thank you
