If triggered by an unauthenticated user, an error is thrown

[jasonvarga]

The commit message contains the current user's username.
If they're logged out, there's no username to get. This could happen when using front-end forms.

We should change username to "unauthenticated user" or similar.

Front End forms work great when logged in, so we just need this little tweak for non-logged in use and we should be all set

Fixed in 2.0.1
