Administrators and uploaders are able to upload files on MediaWiki.org (this site), while regular users cannot. This was done to reduce the increasing amount of junk and copyright violations present in MediaWiki files (and reduce the existing ones), while allowing users who have a legitimate need to continue uploading files here.
Users requiring the ability to upload locally on MediaWiki.org should post a request at Project:Requests.
Uploaders have the following rights, which are also had by sysops:
- Upload files
- Overwrite existing files
- Overwrite existing files uploaded by oneself
- Override files on the shared media repository locally
