plural oversighters

1. A person having oversight; an overseer or supervisor.

   But there was nothing wrong about that because it fell within UN travel guidelines. Suspicious, yes; wrong, no, the “oversighters” said. Meanwhile, cryptic comments abound in the investigators' report, such as, “It is beyond the purview of this report to inquire into the vagaries of airline fares.”

2. A user with special wiki privileges allowing them to hide deleted data from the publicly viewable logs.

   Oversighters are allowed to hide revisions, user names, and other entries in an article's record of revisions (its log) so that only other oversighters and stewards can see them (called “suppression”).
