Administrators, commonly known as admins and also called sysops (system operators), are editors who have access to technical features ("tools") that help with maintenance. For example, administrators can protect and delete pages, block other editors, and undo these actions as well. While the tools granted to administrators are technical and do not convey authority per se, administrators are entrusted with potentially harmful tools. Adminship is granted indefinitely, and is only removed upon request or under circumstances involving high-level intervention (see administrator abuse below).
