Just for future reference, if ever I make a change with my modules or in formatting, is there a "reset" option, or particular files I would need to re-upload to my server to "start over" or "go back"?
PS. I have just purchased "Joomla! A User's Guide: Building a Successful Joomla! Powered Website" by Barrie M. North. Hopefully this book will give me a better grasp of Joomla. Any reviews?
