Thanks, I do understand how i18n works for plugins. I should have asked if there is a way to do this without having to fork or modify the existing plugin. It seems like the answer is no.
Personally, I think this is a lacking feature of NodeBB.
I don't need to do a full language translation but there are 1 or 2 text strings I'd like to change. Is that possible? If so, how can I do it?
Thanks in advance.
