I've been using and teaching others to use WordPress for a few years now. I've finally gotten around to making some tutorials for my students and have put them on the web for others to use. They are "basic user" tutorials and I do use a very customized (hacked) WordPress install to fit my needs, but many of the tutorials will still apply to a standard install.
Just a small way to give a little back for a great piece of software. Feel free to use them if they will help you. I'll be adding more to the list throughout the year as well as tutorials on other software I teach, such as, Audacity, Camtasia, OpenOffice, and PHPList.
