A new plugin for finding out information on the post author is out, called User Bio Popup.
This WordPress plugin searches posts and pages for the nicknames of authors. When it finds one, it turns it into a link which brings up a popup window with the author’s bio and image. It uses the contents of the â€˜About Yourself’ field in the user’s profile for the actual bio, and the image used depends on which of the two methods you select. The options page for this plugin allows you to configure the popup’s heading, width, height, and more. It also is fully customizable with the built-in CSS in the popup template file.
