I remember there being a rule about in Local on Public maps you are only allowed to speak English which helps the mods when there is a problem, so as long as these other forums don't encourage speaking a different language that goes against the rules should be fine to use the translate or other options suggested.
There is no rule pointing towards any other language than English being forbidden in local chat. Sure, that would make it a lot easier for us, but that is not the case.
