This paper tackles three aspects of community-based technological initiatives aimed to support minority groups’ public expression and communication: participation, visibility and sustainability. Participation requires\ud
the active involvement of the community members in various project phases (from design to evaluation), sharing decisional power with project leaders. Visibility\ud
refers to the capacity of community messages to reach a relevant audience outside the boundaries of the community itself. Sustainability indicates the capacity of a project to continue, under the control and management of the local community, beyond its “supported” lifetime. The mutual influence of these three dimensions is examined in general and also in the light of a specific case study: an initiative involving a Romani community in rural Romania, having as main outcome the development of a community website (www.romanivoices.com/podoleni)
