Joomla Tutorial Sites
It takes a while to learn to think like Joomla thinks.
Fortunately, everything you need to know is available on the internet. There are some wonderful resources available online to help you get through the initial learning curve of this powerful system.
And, I've put several of my favorites and most recommended tutorial sources below. Some of these sites are free. Others have a very reasonable charge.
There are a lot of very good Joomla tutorials available on Joomla Tutorials. This site by Brad Baker, one of the Joomla Core Team and a principal of Rochen, a premiere Joomla hosting service.
They have a series of animated tutorials here: http://www.joomlatutorials.com
Compass Designs has an excellent collection of tutorial articles. They are well organized, and well written.

Well known template provider RocketTheme also has a a good selection of Joomla tutorials on their site. Some are specific to their template, but many are good overviews of Joomla in general.
Siteground is a Joomla friendly web hosting service that offers a number of very helpful Joomla resources. These step by step articles are quite helpful.
Joomla core team member Andrew Eddie offers a number of Joomla tips and tutorials on his site, The Art of Joomla. As you would expect from a core team member, he tackles some topics that others stay away from. Good stuff here.
