This brand-new WP plugin removes a tag from a post after a certain date. How would you use it? Let’s say you have a content area called “Breaking News”. That area should show all posts tagged with “breaking”, but you only want the post to be labelled as breaking for one week. Using this plugin you can set that tag to expire from the post. The post is not deleted, but since it doesn’t have the “breaking” tag associated with it, it won’t appear under “Breaking News”.
Raul Martinez, the plugin’s author, says that he wrote the plugin to fulfill a need in his own place of work. It is available through the WordPress plugin interface (search for Expire Tag) or via download.
