Especially on technical issues, it is hard to use/find the right word or sentence in a foreign language (in English for many people here). I occasionally don't post an answer to a question which I know its solution because I have difficulties explaining the solution in English. Therefore, I usually answer code-related questions because no need to write long and sophisticated sentences.
Sometimes, I realize, from his/her name or location, that the questioner speaks in my native language. And it takes a long time to ask him/her some details in English. Therefore I would like him/her to join a new chat room to discuss the question or answer etc. in my native tongue.
Are we allowed to speak in native language in a new chat room? What is the policy in GIS.SE?
