In a community of mobile devices, a non-participating device can be joined to the community if the non-participating device meets location dependent criteria. The device's location can be determined, e.g. be an onboard GPS, from which it can be determined if the device is within a geospatial boundary of the community. The geospatial boundary may be calculated from the locations of community member devices. Only devices that meet the location dependent criteria will be eligible for participation in the community.
