Yesterday evening was the fifth session of this 12 evening training course. I wrote about the fourth session last week. As usual, this evening, the material we were due to cover was described in a dozen Powerpoint slides which the participants received as a handout. See slides 1-6, Powerpoint or slides 1-6, PDF and slides 7-12, Powerpoint or slides 7-12, PDF.
