[rt-users] Language problems

[Vania Guiomar Goncalves]

Hi, 
 
I've installed version 3 of RT.
I found that it automatically detects the language to use depending of
the configuration of the browser... For most of my users it sometimes
the web interface appears in English, Spanish or Portuguese.
 
I don't want this... i want the language to default to english no matter
the browser options. Is there any way to do that? I've searched
everything and haven't found it...
 
Thanks.
