Community-Foundation-to-Community-Foundation (CF2CF) exchanges provide the necessary framework and space for a fruitful mixture of communication, learning end experiences. They are, so to speak, a real-life social laboratory, and like all good labs, they are experimental and hope to bring fruitful results. These cannot always be precisely defined and classified, but on the whole they help participants and their organizations to learn, grow and become stronger in their communities and together better address key challenges of our times in Europe, and throughout the world.
