I'm trying to set-up WordPress for someone that doesn't want a blog per-se, but wants to use WordPress as a lightweight CMS to manage a single-page website. They DON'T want to archive any postings and want only a week's worth of postings visible. Is there some way (via a plugin, maybe?) to limit the number of archive postings kept, and automatically roll-off and delete postings older than a week. (or some arbitrary time-frame.)
