GeoGebra Manual:Administrators
From GeoGebra Manual
Administrators (also known as sysops or admins) on MediaWiki.org are users with the technical capability to protect and delete pages, block users, and edit protected pages, among other things. Some used to work with the Meta-MediaWiki transfer and import of pages between Meta and MediaWiki following the creation of this site and the slight shift of Meta's purpose from documenting the software, but these users now normally get just the transwiki group.
A list of current admins is available here, and bureaucrats here. To request a deletion, see Template:Delete.
