In big cities anonymity often prevails. Only very few know their neighbours. "Nebenan.de" offers an alternative: meeting, sharing, helping - the free online programme seeks to revive things that used to be taken for granted in neighbourhoods, above all offline. To this end, it brings together neighbours who live in the same building, on the same street, or in the same district. The names and addresses of the users are checked beforehand so that no outsiders or search engines can read the information provided. That creates trusts. Thus, "Nebenan.de" is a nucleus for commitment that promotes a sense of community and not loneliness.
