Well, I wouldn't want to set it to nil, because I want this:

Can you please explain: what is the exact the difference between t and
'some ? I looked at the docs and it's not clear to me.

thanks,

What is (setq gnus-fetch-old-headers number) supposed to do? (was: Gnus always downloads 19Mb headers)

This is what I expected to see, too.

It would be very nice to have something like this (don't know if it's
possible):

1. Fetch unread (and ticked) articles.
2. Look at the References and fetch at most N old (parent-) articles of
   those articles.

I switched back to (setq gnus-fetch-old-headers 2000) now. In some
groups (or even some threads?) I see old headers and in others not,
though there should be some very recent parent articles. E.g. here in
gnus.emacs.gnus I see:

I would expect to see (at least some of) the parents of _both_ of your
articles Kai, as the parents are from today, so they definitively are
within the value 2000 of gnus-fetch-old-headers. The highest article
number for g.e.g is around 22162. Changing gnus-fetch-old-headers to
30000 and re-entering the group also didn't show me all expected
parents. I can't see any systematic behavior. :-(

Bye, Reiner.
