Summary: Oops.  Here's how to do it.

Someone had asked how to keep rn from showing articles multiple times,
and I replied "you can't".  Several people have sent mail or posted
articles saying I'm wrong.

Well, I looked into the README file that comes with rn version 4.3,
and sure enough, there's a patch to inews for netnews versions 2.10.1
and 2.10.2 (2.10.3 supposedly has it built-in.)  So, if you want this
feature installed, go talk to your news administrator (except here at
ho95e, where I'm the news adminstrator :~).
			Thanks;
