In my workshops (right up until the latest Unplugged And Making Money workshop) we’ve used Fantastico to install your WordPress. However, HostGator recently discontinued offering Fantastico. Instead, they want you to use QuickInstall. So, when you get to pages 37-39 of the Unplugged And Making Money manual, please use the attached PDF instead.
Follow the steps (there’s only 5 and they’re very easy) and then go on to page 102 of your manual to add a theme, etc.
