UploadWizard became the default upload method, it became highly visible. People were asked to help with the localisation and these statistics show that it worked. As the UploadWizard is part of the MediaWiki extensions, it is quite amazing that for a day half the localised messages of extensions were localisations for the UploadWizard.
The "most used messages" are as visible but they are not as in your face; it is a missing message here and a missing message elsewhere. The statistics show that our readers will miss them. These messages have been compiled again so it is really worth it to check out what you can do for your language.
