Method and apparatuses for multiple types of group membership based on status in applications

A method of supporting multiple types of group membership in a group based on group-member-status as a member of a group in a set of applications includes tracking a group-member-status as a member of the group in a first application of the set of applications for each group member, wherein the first application is operated with mobile devices of some or all of the group members and the mobile devices communicate on a network, and wherein the group-member-status is based on a group member's relationship with the group in the first application; receiving a request for a list of the group members with a particular group-member-status as a member of the group in the first application, wherein the request is from a second application of the set of applications; and providing a list of the group members with the particular group-member-status in the first application to the second application.
