The first user created in Ubuntu is given full sudo privliges by
default. There is no root account on Ubuntu and as such everything is
done through the use of sudo. I probably should have clarified that in
the first email. If Ubuntu ever asks for a password it is for your user
account so that should be the only password you need to remember to use
Ubuntu.
