It's simple, really. There's a built-in script called adduser.
Run it in Konsole as root, or on the command line interface (CLI) as root like so:
For example: adduser spiideyCode:adduser <username>
Follow the prompts, and you'll have added a new user to your system. Check by:after you finish the adduser script.Code:cat /etc/passwd
To have admin rights on your new account, useand below root, add yourself, IE:Code:visudo
Press <CTRL>+O, press enter, and then <CTRL>+X to save and quit.Code:# User privilege specification root ALL=(ALL) ALL spiidey ALL=(ALL) ALL
Edit: Ubiquity does not prompt to add a new user in BT4 Final; it used to in BT4 Prefinal, but has now been removed in BT4 Final.
