The NEPSforum addresses experienced users of the NEPS data as well as persons who are searching for information about the study and the complex data handling. The forum serves as open discussion platform and publicly available knowledge archive. It is administrated and moderated by members of the RDC team. The new service is primarily intended to support the exchange and, thereby, the networking within the NEPS community. It offers the opportunity to post own questions, answers, ideas, suggestions, and comments around the NEPS data leading to a transparent dialogue with other researchers. That way a knowledge base will grow making it easy to find solutions for a number of practical problems and questions. Active participation in the NEPSforum requires no more than a one-time registration.
