Well, then I maintain that these are crossposted articles, and not
natively fetched.

"go away" will happen as per the ordinary expire schedule. (You should

I don't think it will harm your score. I assume slrn is looking at a
single group at a time, the References: and Newsgroups: headers are
unaffected by this option. (So software can still see the article has
been crossposted.) However, the XRef: header will be different, as it
won't include the crossposted-into groups that aren't marked in
interesting.groups.

Example: Assuming you have "groups.a" (but not "groups.b") in
interesting.groups and an article is crossposted to "groups.a and
groups.b", then with create_all_links = 1, fetchnews will create both
groups and link the article into each of these two (letting groups.b
spring to life although you haven't requested it), and with
create_all_links = 0, leafnode will just link the article into groups.a,
without creating and populating groups.b.

In the same example, you can safely kill the links for groups.b with
"rm -r /var/spool/news/groups/b"; you'll need to use create_all_links=0
to prevent the group from coming back.

I hope this clears up what the option does.
