Warning User Enumeration is possible 
The first two user ID's were tested to determine if user enumeration is possible.

ID   User   Login
1   None   admin
2   None   nn000578
It is recommended to rename the admin user account to reduce the chance of brute force attacks occurring. As this will reduce the chance of automated password attackers gaining access. However it is important to understand that if the author archives are enabled it is usually possible to enumerate all users within a WordPress installation.
