This book is aimed at educators. We assume that it's your job to teach, not to have to set up a Moodle site (we assume that this has already been done for you). We are also assuming that if there's any admin task that needs to be performed (a setting that needs tweaking or a switch that needs to be turned on) then your Moodle admin will do it for you. If you do need support in setting up and configuring your site, then check out Moodle E-Learning Course Development (978-1-847193-53-7) by William Rice, available from Packt Publishing.
