This hierarchy is provided as a service to organisations with a widespread
membership. It can be used as a channel of communication to/from their
members, or to exhibit their aims/concerns/activities to a wider
audience. It can also be used to facilitate communication between the members
themselves.

Groups may be created in this hierarchy to discuss matters common
to broad classes of organisations, with groups for individual
organisations of the class in a sub-hierarchy below those groups.

It is to be understood that groups to discuss specific organisations
will not be created in this hierarchy contrary to the wishes of the
organisation itself.
