Delete members
Transfer community ownership to another member

Use member privileges
Member - An end user who belongs to a community and interacts with a community's services and content. A community member has the following privileges:
View general information about the community

Participate in community activities
Visitor - An end user (and nonmember) who views a community's services but who does not interact with the services.
