Disappearing articles

News articles need to "disappear" for a couple of reasons.

Articles marked read in your newsreader

Your newsreader might hide the articles you have read, so that you will not have to wade through e.g. 100 articles you have already seen just in order to find 20 new ones. This behaviour depends on how your newsreader is set up.

Ways to mark articles unread

Expiring articles on your news server

News servers have a finite amount of hard disk space. This is why they must expire (i.e., remove) articles from time to time; they need to make room for new ones.

Example configurations

How to locate an expired article

If a given article has expired from your news server, and you really want to read it, you need to obtain it elsewhere.
