Wikipedia:Sighting

Sighting is a proposed future Wikipedia process in which a privileged editor reviews a suggested change to an article marked for Flagged Revisions. The exact level of privilege required has not yet been decided but may be called Surveyor. The editor can approve the change, so that the new version is displayed by default (as if the article had been edited normally without Flagged Revisions). Alternatively, the editor can reject the change [how: by reverting it?]. [Does a rejection count as Sighting, or does the term Sighting imply approval?] [The editor may also read the change, realise that it is in an area beyond his competence (or his tea is ready), and decide to do nothing, leaving the suggested change pending for later Sighting. Does such a decision to do nothing count as a Sighting?]

The 'sighting' function is in use on the German Wikipedia, and the name may have been influenced by it (see Wikipedia:sichten on the German Wikipedia).

Technically speaking
Sighting is the application of a flag applied to a specific version of a page by a user that has been granted the "review" or "autoreview" right that then sets that version of the page to the lowest level "stable" version of the page.
 * Note: the "draft" version of a page is the most recent version of the page.

A related term, Validating relates more to the quality of the page and is the application of a flag applied to a specific version of a page by a user that has been granted the "validate" right that then sets that version of the page to the highest level "stable" version of the page.
