Abstract: The communications system is disclosed that includes a plurality of devices associated in a group. A server (50) administers communications between members of the group. Preferably, member devices of the group are provided with a client application (52) for communicating with the server (50). In the embodiment the client application is installed on a mobile or cellular telecommunications device, such as a GPRS or 3G mobile handset. The client facilitates communications of the user of the handset with the server, and provides an interface between the underlying device functionality (such as a built-in camera, the device's file system etc.) to allow content to be easily accessed and shared amongst members of the group. Communications between the client application and the server may be performed by XML over HTTP using a GPRS or 3G bearer.
