Now i use:

 

Public Overrides Function FindUserLoginName(ByVal nickName As String) As String
      Return "nisse"
End Function

 

I am logged in as Kjell Ek

 

In Room Administration i write in the form field User Name "kalle" to add moderator.

 

The name that is displayed/inserted is "Kjell Ek"

 

Same problem.
