Administrators, commonly known as admins or sysops (system operators), are editors who have been entrusted with access to restricted technical features ("tools") which help with maintenance. For example, administrators can protect and delete pages, block other editors, and undo these actions as well. Because administrators are expected to be experienced members of the community, those seeking help will often turn to an administrator for advice and information. When the communal feeling may be unclear, administrators may help provide a thoughtful voice in some kinds of consensus.
