Joomla! Tip: Check out our extensive free library of Joomla! Tutorial Videos at HoldenCreative.com (my former freelance business, I licensed these vids a few years ago). We'll be introducing new videos for Joomla! 1.6 to CartaNova soon, but for now you can find Beginner, Advanced and Designer tutorials for Joomla! 1.5 and the older Joomla! 1.0 platform. Feel free to use these tutorials as you wish!
Note: Joomla.org also has some great under-used tutorials in the Documentation area.
