We'll create fresh WordPress site with Best-Of Comments installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Best-Of Comments allows anyone with the ability to edit comments to mark a comment as ?featured? and then featured comments will be randomly selected and displayed anywhere you choose to place the php call to best_of_comments().
You can select how comments are displayed, how many to display, and how much of a comment to display (if comments are longer than the specified word length they contain a link back to the original comment). In the future you will have the ability to limit how far in the past to look for featured comments.
