Hello! I'm Szymon, a member of the Web team working on Desktop Improvements and the Vector 2022 skin. Have you maybe read about this project? Approximately 30 wikis have our new interface as default both for logged-out and logged-in users.
I would like to present the skin to the Hindi Wikipedia and Wikisource communities. Would you be able to translate this message? When it's ready, I'd post it on those wikis and be there to answer any questions.
