Sigh.  If only other system news admins were as responsible as Brian.
Thank you, Brian, for being considerate and asking for advice when
you weren't sure of the answer.

To create a local newsgroup, you can use the "inew" feature for
creating newsgroups and let your distribution as set in your "sys"
files do all the work.  That is, type:

/usr/lib/news/inews -C su.news

and the "inews" program will create an appropriate control message
that will only go to sites that normally would get the "su"
distribution, as stated in your "sys" file (assuming you have your
"sys" file set up right).

The other way is to hand-build an article to do the work for you.
For instance, the following would work:

Newsgroups: net.general.ctl,control
Distribution: su
Control: newgroup su.news
Subject: cmsg newgroup su.news

Make *SURE* you have the "distribution" header in place!
A minimal article like so would also work:

Newsgroups: su.general.ctl
Subject: cmsg newgroup su.news

Good luck!
