You know groups within ResearchGATE as what they are, just groups. But we decided that this is not enough within the world of science - it does not reflect the structure of the research process. Therefore, we have added two features to the groups, what will bring us a large step ahead towards Science 2.0: First, groups can now be categorized, e.g. as an institute, a research group or simply people of similiar interests. It might even be a convention or conference. Secondly, the groups can now be "grouped" with each other, meaning groups can be related to other groups.
