User Groups allow the system adminstrator to specify sets of news groups to limit which users can access particular groups. Two default groups are created, "Default read" and "Default post", which are initially defined to cover all existing groups (both are specified as "*"). The system administrator may create additional groups and may modify the definition of the default groups. Note that users who do not login, use the default groups. This allows the system administrator to limit access to news groups for non-logged in users to a select set of groups.
By using the "!" (negation or NOT), and the "Permit" and "Exclude" buttons, one can create equivalent descriptions. However, the system administrator may find it more convenient to list either the groups permitted, or the groups excluded to a set of users.
