Doug,
When you reply to someone's message, choose the REPly option, rather
than COMposing a whole new message. That way your reply will be "attached"
to the previous message, and people can read them as a continuous thread.
Otherwise, it gets rather disorienting to anybody trying to keep track of
who's saying what to whom, and when…
<And please don't take that as a criticism – we're really glad to have
you participating in the forum, and you're bringing up some very good
points!>
