Last year I missed the annual Exim course in Cambridge owing to being on honeymoon at the time - though I still did the setup for the practical sessions, which was slightly hairy since it was the first time we had done a practical in Cambridge and I was not going to be there to fix any bugs; fortunately there were none.
This year I am in Cambridge, and as well as doing a slightly updated version of the practical, I have also given a talk. The slides are now on the web at https://fanf2.user.srcf.net/hermes/doc/talks/2006-07-exim-course/
