Questions:

1) I'm using Ximian Evolution.  When I display full headers on a
*received* e-mail message, I don't see a <in reply to> header.  ??  (I
can see no headers on messages as I compose them).  Like others, I have
replied and simply changed the subject line (either creating a new
thread on a new topic, or making it match some existing thread)  Am I to
understand that there is a hidden header that retains "subject" info
about the message I replied to?  And now it conflicts with my changed
subject line??

2) When I reply to a message, how am I to know whether it is "buried
down in a thread?"  A message is a message.  I am aware that messages
originate from the group, and that subject lines are the key to
belonging to a thread or not.  Am I missing something?

I want to be a good citizen but if nobody posts "the rules" then ..?
