Under no circumstances should your local newsgroups be named into a
local hierarchy named local.*. Articles will leak and end up on any
other News site that made the same mistake.
For obvious reasons, you just create a local newsgroup. You don't first
issue a newgroup message. That's for all the News sites in the rest of
Usenet to act upon, you know, the News sites to which you don't wish to distribute articles.
Figure out a new name for your local hierarchy that could be unique to
your server.
