Abstract: A system permits a user's activity in relation to a physical location to be associated with a virtual community web site and, therefore, with a virtual community created by the web site. Users indicate their presence at, or association with, a physical location by sending messages from their personal communication devices, such as mobile telephones or Internet-connected computers. Users may participate in activities at the locations by sending such messages, accessing location proxy web sites or via virtual communities. An exemplary activity includes a network-connected jukebox. Users may obtain information about music being played on the jukebox. In addition, the jukebox may display information about music being played on other jukeboxes, possibly in other locations.
