I'm getting the above message when in a group and typing 'a' to Send a Message.  Newsgroups:
name.of.newsgroup, is specified which is listed in the server summary.  Is there any reason why the group
would be unknown?  How can I resolve this warning?

I'm using news.eternal-september.org as my NNTP server, so not sure if
it's specific to it.
