Just finished teaching a class on writing online Help. It went well. It's amazing how old instincts kick in - despite my not having had time to rehearse, I'd prepared just enough material so that with time to answer all the inevitable questions, I finished exactly in my allotted time slot.
People seemed to think it was well-delivered, as well, though I was acutely aware of every "um", awkward pause, or clumsily expressed thought, since we were recording the whole thing for posterity. Not sure if I'll have the guts to go back and listen to it later. Not sure if anyone will go back and listen to it later, but it seems to have served its purpose in the present.
