Communication language on DC

Hi!

Just wondering if communication between client/CH and designers can be in other language (their native for example) than english?

Is there official rule regarding communication language?

Hi there

This is an English site so communication should be in English

I don't find appropriate at all, finding communication in native language between contest holder and designer.
No matter today it is easily to google translation, so potential harm could be detected... but it could be find rather personalized or protectiveness if doing so.
If we choose an English site, than We should all be equal in every sense.

Please, I wish you advise following Contest Holder regarding communication language:
