The whole point of this tutorial is to help with usability, and on that subject one of the things i find slightly lacking in webmin is the mysql administration. Albeit use able its not all that refined. The fix I find for this is installing
phpmyadmin . Its pretty useful for user administration and has a hell of a web interface. Its also really easy to install.
SSH in to the system , as at this point theres no use for a monitor since webmin can take care of just about anything you need...
