You can choose to display the OrderBox interface, as well as
the notification mails to your Customers and Sub-Resellers in any of several
different languages.
To specify this language preference,
1. Go to Settings -> Other Branding Settings
-> Default Language.
2. Select the radio button next to the desired language.
3. Click on Change.
This will change the language on the Control Panels as well as any
notification mails sent out by the
system to your Customers and Sub-Resellers. However, your Customers and
Sub-Resellers also have the option to set their language preference for
themselves. This would over-ride your specified preference, for that particular
Customer or Sub-Reseller.
