As a contribution to the community, I am performing a crude usability test.  For years, bookstores have been selling thousands of self-help teach yourself office application books.  My curiosity focused on a book that my wife recently finished.  I have in front of me an Excel 2003 book and over the next few months, I will follow the lessons in OpenOffice.org Calc and take notes on the differences and intricacies of teaching myself to use a spreadsheet with a book published for a specific application.  I’d like to leave a brief disclosure: I was originally taught on Lotus 1-2-3 and know my way around a spreadsheet very well.  i will try to remain objective by sticking to the book and noting any variance of functionallity thoroughly.  There are one hundred lessons and I will try to perform 10 lessons per post.  Stay tuned for more info…
