My student told me that there is a competition on OSM mapping hosted by "Direktorat Kesiapsiagaan Deputi Bidang Pencegahan dan Kesiapsiagaan, Badan Nasional Penanggulangan Bencana"
The Google Form link for registering the competition is here: http://bit.ly/mapcompetition
The Google Form is in Bahasa (Indonesian), and I don't know (yet) whether folks from oversea will be allowed to join this 'competition'.
From their leaflet, seems there are 10 smartphones as a reward of your kindness in OSM.
btw, this is the official website ... (I'm not even open it yet before I wrote this diary ... lol)
