Membership Information

        Membership-Type ::=     BITSTRING
              ( invitation;
                passive;
                secret;
                reserved1;
                reserved2;
                reserved3;
                reserved4;
                reserved5;
              )

The Membership-Type type contains flags that modify a membership. It is passed as part of both Member and Membership. The flags are:

invitation: The member has been invited, but has not yet accepted membership. Clients should set this flag when adding other users as members. The server may force this flag to be set when adding another person as a member of a conference.
passive: The member is not actively participating in the conference. Passive members do not receive group messages and should not be displayed as active members by clients.
secret: The member does not wish to disclose the membership. Secret memberships and members are cleared before being returned to a person who is not a supervisor of the member or has sufficient privileges enabled.

The remaining flags in the Membership-Type structure are reserved and should be set to false on all new memberships and retained on all existing memberships.

        Member          ::=
              ( member          :       Pers-No;
                added-by        :       Pers-No;
                added-at        :       Time;
                type            :       Membership-Type;
              )

The Member structure encodes information about a member in a conference. It is returned by the get-members call. The fields of a Member structure are

member: The person who is a member of the conference.
added-by: The person who created the membership. This field is zero only if the membership was created before protocol version 10 was introduced.
added-at: The time when the membership was created. This field is meaningless if added-by is zero.
type: Flags modifying the membership.

The contents of a Member structure can be cleared (all fields set to zero) if the person requesting the record has insufficient privileges to see the contents of the structure.

        Membership-Old ::=
              ( last-time-read  :       Time;
                conference      :       Conf-No;
                priority        :       INT8;
                last-text-read  :       Local-Text-No;
                read-texts      :       ARRAY Local-Text-No;
              )


        Membership ::=
              ( position        :       INT32;
                last-time-read  :       Time;
                conference      :       Conf-No;
                priority        :       INT8;
                last-text-read  :       Local-Text-No;
                read-texts      :       ARRAY Local-Text-No;
                added-by        :       Pers-No;
                added-at        :       Time;
                type            :       Membership-Type;
              )

The Membership structure encodes information about a person's membership in a conference. It is returned by the query-read-texts and get-membership calls.

position: The position of this membership in the membership list.
last-time-read: The time when the person last read anything from the conference.
conference: The conference this membership data pertains to.
priority: The priority the person has assigned to the conference. The higher the number, the higher the priority. In the past, priority zero indicated a passive membership. This usage is now obsolete.
last-text-read: The local number of last text read in the conference.
read-texts: Additional texts beyond last-text-read that have also been read.
added-by: The person who created the membership. This field is zero if the membership was created before protocol version 10 was introduced.
added-at: The time when the membership was created. This field is meaningless if added-by is zero.
type: Flags modifying the membership.

A membership record may be cleared by the server (all fields set to zero) if the person requesting the membership has insufficient privileges to see the contents membership, but has sufficient privileges to know about the person.
