For those who have registered, the slides from the recent Tallinn conference are here, with updates from Austria, Switzerland, Slovakia, Portugal, Netherlands, Poland, Czech Republic, Italy, Spain, France and the UK.
The conveners are Prof Joris VAN DE KLUNDERT at firstname.lastname@example.org, and
Dr David MANLOVE at David.Manlove@glasgow.ac.uk .
I'm a (non-European) supporter of this effort.
