Folks in Delhi interested in having a mapping party, please get in touch with me 
We’ll use Vespucci, the Android OSM editor, to improve OSM coverage in the area we decide to meet. We’ll decide on a time and place which suits everyone.
If there are any first timers, we’ll help them with creating an OSM account, installing Vespucci, and getting started with their first edits…so get in touch with anyone you think would be interested!
You can respond here, PM me over osm.org, or (ideally) get in touch over XMPP - contrapunctus@jabber.fr
