This is part of the azurecurve ClassicPress Plugins which introduces the plugins I have available for ClassicPress.
The plugin I am going to cover in this post, is an existing one which has been brought up to coding standards; Post Archive.
The Post Archive is usable via a widebar widget and page-index shortcode which display a post archive broken down by year and month.
The sidebar on this site contains a Post Archive widget showing the posts made since June 2011.
The plugin can be downloaded via my Development site.
