Using cron instructions unclear....at least to me

Hi,

First of all, why do we need a cron job set up anyway?

Second, in you cron command string you have:
*/5 * * * * /bin/wget -O /dev/null "http://stackideas.com/index.php?option=com_easydiscuss&task=cron

I assume that we replace stackideas.com with our url...correct?

Thanks,
Dom
