Please clarify the "etiquette" speaking in english

[Sir Baron]

New players often want to ask something and can't because admins enforcing English-only policy.

That leads to new players decline of playing this mod.

While I agree that speaking languages other then English in game chat should be minimized, sometimes it's critical for successful defence to say something in new player native language so he can understand and does not wipe the whole team.

Separated language-board on the forums where new players would be able to ask their questions and not corrupt game chat would be nice addition. Mainly I speak about Russian and German ones as they're most spoken languages in game-chat outside English, may be Polish one too. Many games have "other languages" section on their forums, I'm surprised that NI doesn't.

Generally admins have no problem with a question and answer in some other language
When I start dropping red text is when people are talking in it for 2-3 waves
