@AKlapper: I know I can do that, but for this topic I cannot help. My reply was general. There are some reasons why resources get marked as fuzzy, and there's also a way to mark an existing translation as being fuzzy again, without deleting it completely (which is bad as it cancels all its history), when it is still actually requested and a fuzzy translation may still have contents whose translation is still unclear (frequently this is because the source message is ambiguous, and lacks documentation about its usage, e.g. missing clear distinction between isolated verbs and nouns in English, or multiple meanings of the same orthographic term). Another reason is that most of the message was considered OK, but there's an issue in the existing translation caused by an update in the source message. Making some resources fuzzy is enough to solve those issues without deleting them. Another viable reason is that a single resource for a translatable page is marked fuzzy (only copying the English source) in order to force the translation tool to create the first version of the target page (which has incoming links to it): even if the whole page is still not translated, it is still best that it displays the English fallback content, even if the whole page remains to be translated. Finally another reason is that it also allows importing resources from an older translated page (but whose translation was manual, still present in its history, and its existing content will be manually parsed to import and convert it to the translate tool. So the "fuzzy" mark is an intermediary step before looking for other existing pages to find the terminology previously adopted. It's a useful feature, even for actual translators.
