    Network News Transfer Protocol (NNTP) Additions to LIST Command

Abstract

   This document defines a set of enhancements to the Network News
   Transfer Protocol (NNTP) that allow a client to request extended
   information from NNTP servers regarding server status, policy, and
   other aspects of local configuration.  These enhancements are made as
   new keywords to the existing LIST capability described in RFC 3977.

   This memo updates and formalizes the LIST DISTRIBUTIONS and LIST
   SUBSCRIPTIONS commands defined in RFC 2980.  It also adds the LIST
   COUNTS, LIST MODERATORS, and LIST MOTD commands, and specifies
   additional values returned by the existing LIST ACTIVE command for
   the status of a newsgroup.
