I'd like to ask you to translate two banners. We encourage users to try out the new skin. Later, we'll ask them to give feedback.
The first banner is already visible on some wikis (see the languages covered already[1]), and I set it up on more wikis as the translations are added. On Phabricator, you'll find more information on why we're doing this:
