There are two types of community members, community owners and community users.
Community Role Management portlet lists all registered members and allows the community owner to add and delete users from the community. Community owners can also transfer ownership of the community to a registered member. Only community owners are given access to the Role management portlet and can delete a community. Registered users can join any community and leave a community at any time.
To become a registered member of a community, a user has to create a username and password. Only a registered member can create a community.
Community members can add and search for community content available in discussions, surveys, polls, calendar events, calendar tasks, and the database.
