Using this site, people can organize social activity, find like-minded persons, campaign advocates and collect donations.
Very complicated project - a lot of social functions, messaging system, user roles system, small wiki system, activity binding to admin regions - district, city etc for simple navigation around closest campaigns.
Map integration is noteworty. Hierarchial structure of admin regions of all countries is stored in database, so that user could see what's happening in his district or block. During map navigation, appropriate regions are highlighted on map based on zoom level. Data transfer is optimized so that only needed information is loaded from server.
