We'll create fresh WordPress site with A Year Ago Today installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Plugin that shows links to posts that were posted exactly one year ago as a widget in the sidebar. Posts are listed by popularity based on the number of comments.
If there were no posts posted a year ago then the widget will not show anything in the sidebar.
User options: Title and number of posts to show (default “a year ago today” and “1”).
