This content mambot/plugin takes automatic actions when Joomla! content items reach expiration date. It can archive, trash or purge your expired items, and can be configured to send email when actions are taken. Useful with newspaper-like websites(to auto-generate news archive), or in conjunction with automated content item generators, such as Phlooid's news aggregator. Can be also used (obviously) as a reminder for item expiration.
Make sure you download the latest 1.0.1 to ensure archived items can be accessed in frontend.
The online guide is also updated, 1.0.0 users please read the guide to fix your frontend archive.
