People all over the world are contributing as volunteers in developing countries to apply and build others' capacities in information and communication technologies (ICT). The United Nations Information Technology Service (UNITeS), led by the UN Volunteers programme, promotes volunteering as a fundamental element of successful ICT4D efforts, and promotes ICT as a tool for volunteers engaged in development. In conjunction with the World Summit on the Information Society (WSIS), UNITeS is gathering and posting examples of such "ICT volunteering", and linking each to its relevant Millennium Development Goals (MDGs) and MDG targets.
