Administrators and uploaders are able to upload files on Wikimania-wiki, while regular users are not. This was done to ensure that all free material is uploaded to Wikimedia Commons while still allowing certain materials, with legitimate use on the Wikimania-wiki, to be uploaded even when it would not belong to Commons' scope. (T225505). Examples of such files could be logos of partners or sponsors.
Uploaders have the following rights, which are also had by sysops:
- Upload files
- Overwrite existing files
- Overwrite existing files uploaded by oneself
Administrators can appoint and remove uploaders.
