Audiqueen displays the name of the user in the ribbon.
By default this is the short name as it appears in the User Edit screen.
If you prefer to have the full name (last and first name) displayed, this can be set in the configuration. For this you need administrator rights. Open the administrator tool (click on the Audiqueen icon in the top left corner).
In the Administrator Tool, click on Global Settings. Then scroll down to the tab General, where you find the parameter UseFirstNameAndLastNameInsteadOfUserName. Change the value to True.
The next time you open Audiqueen, it will display the full name rather than the short name.
