back in the day when Novell was used i was on work experience and given the role to look after the network, while logged in as the admin account i was cleaning up user accounts and thought it would be a good idea to delete the admin account and create a new one, for some reason back then it allowed me to delete the master admin account i was logged in under and from that point had no privileges to create user accounts, resulting in the network no longer having an admin account to maintain the network. I wasn't popular from a while.
