The Hypergrid International Expo is an annual event where people whose first language is not English get the chance to speak about their grid, their projects, their inventions and their opinion- in their own language - with subtitles for the rest of us - about places in Opensim.
While the emphasis of the presentations is to give non-English speakers a voice, the HIE Park is full of publicity booths that celebrate and inform you about all kinds of places in opensim.
