WP Custom Taglines adds a meta box to your posts and pages with two options, Enable Custom Tagline, and Custom Tagline Content. Checking 
“Enable Custom Tagline” will cause your site to display the contents of the “Custom Tagline Contents” field on your site when that post or 
page is viewed, instead of the sitewide tagline.

Custom Taglines

WP Custom Taglines allows you to specify a custom tagline for each post or page that will override the sitewide tagline for that post or page.

Version 1.5.3 
* Fixed conflicts with other plugins / admin features
Version 1.5.2

Version 1.5.1

* Switched to use jQuery that is bundled with WordPress to avoid jQuery.noConflict()

</ul>
Version 1.4
<ul>
<li>Tagline links may now have an optional target</li>
