Choosing "Employee" is correct if your organization has a membership, and you are wanting to enroll as an employee.
Choosing "Member" is correct if you are enrolling as a paying member of the organization.
"Newsletter only" is not a TBTF membership, but rather a complimentary subscription to receive our e-newsletter. You will not need your login or password other than to enroll. Additional member benefits will not apply; such as access to members-only areas of the site and member rate discounts for events.
