Check out the 'T' command in the man page. From the selector, you may
select the thread (+), junk the thread (j), or clear the auto-selection/
junking for the thread (c). On the article level, you may also select an
article and its replies (.), junk an article and its replies (,), or
clear the auto-selection/junking for an article and its replies (C).

Here're two ways to use it:

(1) While reading a thread, hit 'T', then hit '+' at the prompt which 
follows.  This dumps the message-ID's of all the articles in the thread 
into your killfile as "followup-selection" commands, so that all 
follow-ups to them will be selected automatically in the future.  As the 
articles expire, so do the corresponding selection commands, so you don't 
have to worry about cleaning out your killfile.

(2) After selecting one or more threads in the thread selector, type 
':T+' and hit 'return' or 'enter'.  This does something similar to the 
above.

Use the -p option, which tells trn to auto-select your postings and
their replies as it encounters them in the various groups you read.
The -pp option selects the article you're replying to, and any replies
to it including your own. Very handy. The man page explains various
other options.

If it seems some threads with your posts aren't getting selected when
you first enter a newsgroup (especially if you crossposted a followup),
you may also want to set the -a option. Without -a, trn enters a group
with the minimum processing necessary, and that doesn't include scanning
already-read articles (that's what the -a option is for). In such a
case, the crossposted group doesn't have an auto-select command for your
posting until after it scans all of the already-read articles in the
group and finds that there's a posting from you that it should be
processing. At this point the selector has already been displayed and so
you probably don't see the fact that some followups just got selected.
