Hello,
there are many files in the de.wikipedia that are automaticly tagged with nocommons, because they should have individual review. That is important because the PD-tags are often not enough for Commons. But there aren't tags, which are enough for Commons, for many PD file, that we could import to Commons, on the de.wikipedia. For example: There are many PD-alt-100 images - images that are older than 100 years, where the author in unknown -, that are older than 120 years (for example de:Datei:''Marie'' Haug ∞ Carl Ferdinand Pistorius, Foto Neapel um 1862, Abzug auf Albuminpapier um 1862.jpg), so that we are able to import them to Commons with PD-old-assumed. But the FileImporter, doesn't allow to do anything, if there a NoCommons-tag. So I think, we should allow to use the FileImporter for File with NoCommons. The FileImporter should make a warning text to the NoCommons Tag, and the User must add the right Commons-tag, before he/she Import the File.
