Dear concern,
Greetings!
Introducing the Endangered Language Project, a Google affiliated project about the information and awareness of endangered languages of the world. Bishnupria Manipuri is one of them. They have a page for it: Bishnupria, where there is a place for submitting sample of the language and submitting some documents on it. I am not a speaker of Bishnupria Manipuri, so I can't do that. I wish somebody from this community can do that for the sake of the language.

But for a starting, I submitted the information about the Bishnupria Manipuri Wikipedia; if they find it rational, they will add it.

(I am afraid I'm not a native speaker, therefore the message is in English for a common language.)
Thanks for your attention.
