[WikiEN-l] How do I respond to the right thread, when I'm receiving digests?

[Christopher Maloney]

Sorry, this is probably a stupid question.  I've just joined the
mailing list, I read the welcome email and the about page, and can't
find the answer to this.

I configured myself to receive the message digests -- there's way too
much volume on this list for anything else.  I want to respond to a
particular thread, though, and can't see how to do it easily.  Is it
just a matter of copying the subject line?  Actually, I'm pretty sure
it's not, because I see several cases of duplicate subjects which are
separate threads.

Thanks
