                onPresence: function(presence){

                    var contact = $("<li>");
                    contact.append("<a href='javascript:void(0)'>"+ presence.from +"</a>");
                    contact.find("a").click(function(){
                            var id = MD5.hexdigest(presence.from);
                            var conversation = $("#"+id);

                                openChat({to:presence.from});
