You could also fire the message on actual success by adding an event listener for ```didCreate```, i.e.

```javascript
model.on('didCreate', function(record) {
  alertify.success('Added user "' + newUserName + '".');
});
```

and similarly ad a listener for ```becameError``` and notify of that.

More of a usability thing than an actual issue though so I won't block either way.
