Yes. AllEasyWay is available in 17 languages, and the Community follows the language set in your preferences: titles, buttons and menus appear in your language.
Posts written by your neighbours stay in the language they were written in. So you'll sometimes come across posts in another language, which is normal in a multicultural neighbourhood.
To talk with a neighbour privately, the chat offers automatic translation to help you understand each other, with a button to switch between "Translated" and "Original".
