+If compiled with <emphasis>--enable-nntp</emphasis> option, Mutt can
+read news from newsserver via NNTP.  You can open a newsgroup with
+function ``change-newsgroup'' (default: ``i'').  Default newsserver
+can be obtained from <emphasis>NNTPSERVER</emphasis> environment
+variable.  Like other news readers, info about subscribed newsgroups
+is saved in file by <link linkend="newsrc">&dollar;newsrc</link>
