Great news: please ring me and Nick Doiron == http://twitter.com/mapmeld in
the coming week so we begin to engage the growing OpenStreetMap community
professionally, beyond just Nepal, but yes also involving Nepal.

(Nick is flying to the UN June 6-8 (http://stateofthemap.us in NYC) so it's
very important we have our ducks in a row to recruit professional
volunteers then!)
