issue #22351:Multiple Sites should not be allowed in postbooks

I tend toward the following style:
```JavaScript
function myfunc() {     // or myfunc = function() ...
  var result = false;   // pick the safest default
  if (something_good_happened) {
    do_more_stuff;
    result = true;
  }

  if (debuggingIsEnabled) { console.log("myfunc returning " + result); } // optional
  return result;
}
```
