Systems and methods for creating and sustaining cause-based social communities and for creating social communities around a specific cause using mobile wireless devices and the global network of computers are described. The system has a cause-server on the global net, a cause-message originating mobile device and a ring of mobile devices. The ring has a first ring, directly reachable by original mobile, a second ring, reachable by mobile devices of first ring, and a third ring, reachable by mobile devices of the second ring of mobile devices and so on. These rings enable a cause-message to spread out in rings globally or regionally. The cause-server hosts functions that (i) enable creation of a cause-image message, (ii) distribute the cause-image to mobile devices, (iii) create a real time map of the distribution, (iv) enable display of the map updated periodically, and (v) archive the cause-message data for subsequent search/retrieval.
