Here is an example:
http://www.acespot.net/index.php/tournaments/16-sign-up-saturday-29-november-2014-20-00-utc
As you can see, Ccomments is displaying the actual name of users and not their username/nickname. As you can understand this is not really a desirable thing. However, in the settings The Use Names option is toggled No, so I dont really know where to go from here.
Help is appreciated
