No, you are welcome nothing wrong to ask a question. As far as I know, you should click translate button and select your language. After that, select a resource and start to translate resources strings.
I just checked files_sharing and did a review for already translated stuff, but I see no option to save that review. It seems like translators and reviewers need different permissions. Who can change that or is there some policy that allows only OC GmbH staff to review the translations?
