<p>This plugin is intended to make the comment-moderation for the blog-owner a little bit easier. It does not detect comment-spam on its own. To successfully prevent spam, it should be used as an addition to the spam-protection provided by Akismet and Spam Karma.</p>
<p>This plugin adds a small button to every comment. This button will only be visibly to a logged-in blog-admin (that is a registered user with a user-level of 10).</p>
<p>When you press this button, the URI of the commenter will be replaced by the URI you can specify at the plugin?s option-page.</p>

Comment URL Control

This plugin will allow you to remove an unwanted author-URI entered by a commenter with one single click of your mouse.

<p>Pingcrawl aims to replicate WordPress.com’s “Possibly related posts” capability. It queries Google Blog Search for related blog posts (based on tags, or the post title if there are no tags), tries to verify that they are pingback/trackback compatible sites and, if so, adds links to such posts to the end of each blog post where it is invoked.</p>
<p>Scope-limiting configuration options are included to enable Pingcrawl to fit any WordPress installation’s memory/execution time budget.</p>
<h3>Licence</h3>
<p>Pingcrawl is free software released under the GPL. If you find it valuable, you’re invited to make a <a href="http://www.nostate.com/support-nostatecom/" title="Donate with PayPal, MoneyBookers, etc." rel="nofollow ugc">small donation</a> toward its ongoing support and maintenance.</p>


Pingcrawl

Pingcrawl adds a "Possibly related posts" capability by querying Google Blog Search for post tags and pinging the results.
