Which group of members is only allowed to attend meetings as observers?

The group of members allowed to attend meetings strictly as observers is indeed Class F members. This designation typically refers to individuals who are not active in the competitive sense within the organization but still maintain a connection through their membership. Class F members do not have voting rights or the ability to participate in discussions that shape the organization's direction, which is why their role is limited to observation.

In contrast, Class A members and active members generally hold responsibilities and rights within the organization, allowing them to participate fully in discussions and decisions. Nonactive classifications could refer to members who might have certain limitations on activity but are still more engaged than observers. Understanding these distinctions is crucial for recognizing the roles and responsibilities within the golfing community and its governing bodies.
