Manage thematically oriented groups within the portal.
2.Use Case Definition
Support for thematically oriented groups within the portal is important for providing a high level organizational structure to the content and presentation of the materials provided by the portal. This use case documents the capability of portal administrators (Operators) to create topical groups on behalf of users that propose the creation of such communities, and the capability for users (acting in the role of community manager) to manage those communities.

2.13.Notes and Issues
Degree of delegated authority provided to community managers (as opposed to portal administrators) needs to be clearly defined. Being able to delegate all day-to-day management authority to community managers would be highly desirable, but what additional authority should be vested in them?
Community status conditions should be defined to facilitate management: i.e. Active, inactive, public, private, deleted. Use of these status flags will streamline the 'publication' process for community areas.
