MMC Posavje was a programming unit attached to Krško Youth Centre, that made a part of M3C Multimedia Centres Network of Slovenia. At the time the MMC provided free Internet access and information technology equipment for digital video and audio production, graphic design and software development as a creative resource for members of the public. Several educational and intermedia artistic projects were organised in its numerous facilities: a cyber café with the gallery, a multimedia studio with two music practice rooms, a computer project room and a multimedia multifunctional lecture room.
The Troblja.info cultural portal has been operated by MMC Posavje since 2003 in order to announce the latest creative happenings in the Posavje region. It is one of the sources for the Kulturnik.si aggregated database of cultural events.
