This plugin for WordPress 2.8 and above allows you to insert a simple table listing of issues from a Mantis Bug Tracker 
into a wordpress page or post. The plugin is perfect for projects which utilize WordPress for their news/content 
management, but also utilize Mantis for their bug tracking/issue tracking
Usage currently is simple:
<ul>
<li>Set the URL to the Mantis API (usually <code>http://example.com/mantisbt/api/soap/mantisconnect.php?wsdl</code>)</li>
<li>Set your base URL for links back to your tracker (e.g. <code>http://example.com/mantisbt</code>)</li>
<li>Set up a user in Mantis for wordpress connectivity – provide WP Mantis Tables with the username/password</li>
<li>Provide the project ID # for the project you want to view</li>
<li>Place <code>[MantisTable]</code> in the page/post where you want the table to appear.</li>
</ul>
Optionally you can set the table background color for statuses, and change the names applied to each status level.
Plans are under way to extend this functionality into a full Mantis plugin – to allow for many features including – 
(All coming in the future… eventually):
<ul>
<li>Limiting the number of issues posted / paging through issues</li>
<li>View an issue details and notes through WordPress popup</li>
<li>Allow anonymous issue reports through a WordPress form</li>
<li>Ability to filter results by version, status, category, etc. within the <code>[MantisTable]</code> tag.</li>
<li>Change logs / roadmaps</li>
<li>Consolidated WordPress/Mantis plugins</li>
</ul>
