Dragon Design has a new plugin out for WordPress that allows you to add information on articles posted on the blog. This could be a great plugin for those that have multi-author blogs, or just want to end with a preset tagline on every post.
This plugin lets you display a custom signature at the bottom of your posts. Simply type the text you want in the options page and configure it to display on every post, or manually display it by adding the trigger text wherever you like. You can also add in author information using the included variables – login name, first name, last name, nickname, email address, website, and description/bio. It get this information from the author’s account settings.
Grab it from Dragon Design’s website.
