How to add a new group

I think the last time I added a new group I had hair.

Anyway, from the group screen, I press "a", and I
enter 
alt.os.linux.debian
and I get an error message:
"alt.os.linux.debian does not exist". 
Well, it does, but I'm doing something wrong: 
The following entry:
alt.os.linux.debian:alt.os.linux.debian
is in my ~/.jnewsrc.dsc.
So what else do I need to do?

thanks
  (using slrn 0.9.9p1 on ubuntu 10.04)
