A microcommunity for preschool is a community for parents, teachers and other people involved in a preschool child group. The community is a tool for distributing and exchanging information and complements the traditional face to face communication and paper notes in that it makes information available from other places than the home and the preschool facilities. We present a first design iteration for preschool microcommunities with parents and teachers. Teachers have worked with a prototype tool to create microcommunities that has been made available to parents. We present a set of design principles for preschool microcommunities and a new design of the tool.
