Restoring threads that have been read/replied to

[Alex Bennée]

Hi,

Due to issues with gmail's IMAP handling I've switched to interacting
with my development mailing lists via gmane's archival service. I've
having some problems understanding how the thread expiration policy works.

I've been using T k (gnus-summary-kill-thread) to kill threads I'm not
interested in. However there are a bunch of threads that I reply to or
want to keep track of. However I'm finding after I've read them they
disappear. If a reply to one of the threads appears I can't read it in
context to the rest of the thread. So a quick question:

  - can I re-fetch a whole thread based on the references in the post
    that is visible in my summary?

So far I can hi ^ (gnus-summary-refer-parent-article) and find the
parent article again but what I really want is to fetch the whole thread
with all it's context.

Ideally this would be automatic for any thread that I've either posted
and has replies or one that I've replied to.
