Hello,
Rafal, read the email. He says he already translated content in Zanata. Therefore, he's approved as translator in a language team. From what I understand, he's waiting (or was waiting) for approval in the international localisation team.
Joakim, you don't say but from your surname I'd assume you're either Norwegian or Sweden. Am I wrong? Or maybe Danish. In any case, welcome aboard and glad to have more translators for Scandinavian languages. Besides this, and just for your information, you can install Fedora in dual boot on a MacBook. For details, you can check documentation (including blog posts) and drop a line to the QA team. Some of them have Apple laptops with Fedora installed in single and dual boot and know what to do and how. Last but not least, don't hesitate to ask any questions. We're always here, although sometimes it takes us a while to respond (sorry for that!).
Kind regards,
Silvia
