Only If you have more than one board. 

Each board has its own Subscriptions & Mentioning Settings, for using different email content for different boards emails.

Notice that in the Subscriptions & Mentioning Settings are two Save Buttons:

Save Options for All Boards and Save Options, you must use Save Options, 

We're building a multi-language website and using wpFORO.

I was wonder if there's a way to send the subscriptions emails in multiple languages?

I know I can edit the HTML emails in the settings, but is there a way I can send emails in multiple languages?

Thanks in advance
