Just using nnsoup won't mean that your postings and mailings end
up in SOUP reply packets automagically.  You have to work a bit
more for that to happen.
The nnsoup-set-variables command will set the appropriate
variables to ensure that all your followups and replies end up in the
SOUP system.
In specific, this is what it does:
(setq message-send-news-function 'nnsoup-request-post) (setq message-send-mail-function 'nnsoup-request-mail)
And that's it, really. If you only want news to go into the SOUP system you just use the first line. If you only want mail to be SOUPed you use the second.
