Hello Zoran and others,
I am not sure to understand what message you write about, however all messages seem to be translatable inside dedicated aggregate group thanks to Tacsipacsi:
You can access to this link from Tech News headers: “Translate frequently used templates“.
Zoran, a message in a big yellow box (if I understand you correctly) is aimed at translation administrators, is not part of the page, and is temporary. Therefore it can be ignored for a few days.
Hello Vira,yes, I thinked on it. And I know that it isn't part of that page, and I suggested that it should be translatable also, like a "draft" template.
