I have received a very generous offer from Bernard J. Poole, a professor at the University of Pittsburgh. He has a series of LibreOffice Tutorials and has asked me to publicize that they are available free of charge to all of our LibreOffice fans here and on Hacker Public Radio. You can find his tutorials on his web site at http://www.pitt.edu/~poole/. He is particularly aiming his tutorials at educators who might use LibreOffice in the classroom.
Please note that these files are available for free, but he does ask that you let him know if you are interested in using his tutorials, particularly in the classroom. And there are some LibreOffice files that accompany the tutorials which are available by writing to him.
