You *do* need to send users a warning. They system will send a message to
all users that it is going down, and they will be chucked off immediately.
It is curtious to give them at least 10-15 minutes notice before chucking
them off. You can do this with options to shutdown (which I can't
remember right now...)

Um. You can't do init 1 unless you are root in which case you can change
your password just by editing /etc/shadow (or passwd on an unshadowed
system) and deleting the password, then use passwd to set a new one.

There is a command 'killall' which comes with many distributions. You can
do 'killall process_name' to kill all processes with that name. A word of
warning though - in Solaris and some other unices, killall kills all
processes you own...
