We understand and translations can be accepted if the original txt is completely translated and if users have difficulty in communicating, but English speaking users can always have doubts about what is written in foreigners languages texts, Mods too lol, so better to avoid to use multiple languages. That's why ,I think, test3r made his post.
After all we have this rule, wrote by our Superadmin:
At point n 8) - "BOARD LANGUAGE IS ENGLISH: Do Not post messages in any language other than English, we have native language sections if you wish to write in another language.
All posts should be posted in ENGLISH language ,if you have difficulty with this, please use an online translator."
Thanks for your cooperation and politeness
