  • a first member of the user group notifying the server that the first member is present, thereby prompting the server to provide members of the user group presence information about the first member;

    the first member during the communication session sending a proxy request to the server to enable a second member of the user group to change the presence information about the first member; and

    the server granting the proxy request, thereby enabling the second member of the user group to change the presence information about the first member during the communication session;

    the server receiving a request from a member of the user group other than the first member to change the presence information of the first member;

    the server checking to see if the member making the request to change the presence information of the first user has received a proxy which enables that member of the user group to change the presence information about the first member;

    if the member making the request to change the presence information of the first user has received a proxy which enables that member of the user group to change the presence information about the first member the server changes the presence information about the first member as requested; and

    if the member making the request to change the presence information of the first member has not received a proxy which enables that member of the user group to change the presence information about the first member the server refusing to change the presence information about the first member;

    wherein the proxy enables the second member to change the presence information of the first member only during the communication session in which the proxy was issued.
