  properties : {
    title : { type : "string" },
    body : { type : "string" },
    author : { type : "string", readonly : true, optional : true },
    created : { type : "integer", readonly : true, optional : true },
    modified : { type : "integer", optional : true }
  },
  prototype : {
    initialize : function() {
      this.author = getCurrentUser().id;
      this.created = (new Date()).getTime();
    },
    onSave : function() {
      this.modified = (new Date()).getTime();
    }
  }
});

2. Create user: User.createUser("admin", "asdf");
