Supersede
The verb supersede (from English to supersede = replace) referred to Usenet sending an automatically analyzable by software recommendation to override a Usenet article by a newer one. A normal posting is sent, supplemented by the following header :
Supersedes: <messageid@server.example>
Newsreaders , i.e. the programs with which one participates in the Usenet, generally have a function (button or the like) called "overwrite message", "supersede Usenet message" or similar to generate and send a supersede message.
