This is a Jubilee Issue of the Bulletin – the 50th PIMA Bulletin. The first was published in 2015, just a few pages long, and only shortly before the first General Meeting of what is our PIMA today. Most of the previous issues were edited by Chris Duke as former editor, and now after his untimely death we are trying to follow his energy, scope and route. It is also a Special Issue on CONFINTEA; actually the second PIMA Bulletin that tries to ensure action and follow-up on what happened nearly two years ago.
