The Antiwar Campaign in Zagreb and the Center for Antiwar Action in Belgrade decided to set up their own BBS network. In both cities, the BBS was installed in a computer which was in use for other purposes during the day and also had to use a telephone line which was normally used for voice communication. Letters could be sent overnight from Zagreb to Belgrade and from Belgrade to Zagreb. Network and associated networks. Gateways to other e-mail networks are also available.
Users can send and receive messages from anyone with a valid Internet e-mail address.
Since April 1993, it uses the ZTN to have better contact with it's member orgnisations working in Serbia and Croatia. International financial mogul George Soros' Open Society Institute, which is one of the main sponsors of the network, uses the ZTN too. By the summer of 1993, there were a total of 375 users in Belgrade, of which only 7 were groups. In Zagreb there were about 125 users including 27 groups. The large amount of individual users in the Belgrade BBS was due to the fact that other channels of electronic communication from Serbia to the outside world were still very difficult, if not imposible.
