I need a plugin that allows user to "vote up" or click a "like" button. The plugin must use the post meta fields because the sorting for the entire site will be by the sum of votes, descending. Bonus points if the algorithm could support a trailing time period. e.g. Top "likes" for the last 90 days.
Thank you. I've examined most of the popular plugins and most of them force us to use multiple stars or do not support the post meta field in the database to allow sorting.
Please note that I am needing to sort ALL posts, not just have a widget displaying top posts.
