We created an NT Account dedicated to just setting up "Corporate
Notifications". Basically we logged in as this account and setup
subscriptions to the various items (docs, cats, folders) and used the SMTP
address of a Distribution List. Unfortunatley, this doesn't translate into
individual Subscriptions that the users can manage themselves but at least
is a way to notify them of changes without makeing them sign up. If you
REALLY want to preconfigure subscriptions, you will probably need to do this
programmatically.
