I have been teaching occasionally since 1998, when it turned out I knew more than the tutor on an Advanced Photoshop course.
Since then I have taught schoolchildren, teachers, adults and individuals in the use of Illustrator, Photoshop, Flash and Dreamweaver.
The most enjoyable so far was Breeze 2002, an international schools music festival, where 3 of us worked with a group of schoolkids creating a daily video catalogue of events. We had to have all the day's videos filmed, edited, output and posted on the web by the next morning. Very hard but very rewarding.
