We've been talking about the 3Rs since Russell and Burch in 1959, and periodically we add additional Rs. But do we all really mean the same thing? We use a wide variety of ways and tools for our communication. We communicate in different languages, with different intentions even within and outside different groups. Different previous knowledge, interests and ideas influence what we want to send out on the one hand and what we hear on the other. Here we would like to support you as RepRefRed Society. Be it as a knowledge transfer platform, as a mediated instance within the 3R community or in the preparation of 3R topics to support you in your communication in the best possible way.
