The .fmp[x]Berlin 2015 conference is a big meeting of FileMaker developers from around the world in the center of Europe.
It's planned for 4 - 6 June 2015 in the Upstalsboom Hotel Friedrichshain, Berlin, Germany.
So mark the dates in the calendar and plan your trip to Berlin. Tickets are available mid January and the conference is in english. Last time I think there were 75 people coming.
