Setting up a cron job in Webmin Virtualmin GUI on Linode with Lenny

Seriously, It sucks to be the girl with no UNIX experience who needs to set up seemingly simple things like cron jobs. I don't understand the commands or what -0 -q -t means no matter how many times I read the handbook page on Drupal.org. I just want to know the command that works to I can plug it in to the GUI interface wherever I am, or I would even go so far as to run a command via ssh in the command line (shudder).
For the past few weeks I have been working within my first, very own VPS on Linode running Lenny on Debian 5. My friend Christefano helped me set this all up and I also installed webmin virtualmin cause I like that sort of interface. It works for me.
One of the things I have avoided until now is setting up a cron job for the site that I am working on.
Today I decided to tackle it because I need to go live with my site very soon, and my news feeds and backups rely on cron. Not to mention Drupal needs cron for "washing the windows and taking out the trash" so to speak.
So, in case you are running the same sort of set up I am and you are like me a total boob when it comes to cron, here is the command that finally worked for me:
 
/usr/bin/wget -O - - http://www.yoursite.com/cron.php
 
I almost jumped out of my skin when this worked.
 
I hope this helps someone out there.
 
NB
Update: So if you want to know where to access cron jobs, choose "webmin" and on the left will be a "system" dropdown with schedule cron jobs as a choice. From there you can create a new cron job or edit one.
