There were many people, friends and co-workers have contributed a lot of valuable assistance. A special thanks to Ted Kaiser and Dave White who's advice and expertise was invaluable in the beginning of this guide.

Credit also should be given to the hundreds of unionized & non-unionized workers, students, and business people throughout Southern Ontario who have taken these courses and shared valuable feedback which has helped shape this resource.

Thank to the thousands of writers, educators and resources providers who have given their knowledge freely through their feedback, websites and through newsgroups/discussion groups.
