The last release includes new options to replace the nofollow only when the author posted X comments before and put back the nofollow when some blacklisted words are matched. The replacement of the nofollow is also based on the users type (registered and visitor users). Every option cna be customized by the options page “NOFF”.
NoFollow Free now is multilingual, it supports English, Spanish, Italian, German, Turkish, Swedish, French, Portuguese, Romanian, Russian, Danish, Arabic, Croatian, Norwegian, Indonesian, Dutch, Hungarian, Chinese, Japanese, Polish amd Finnish languages.
Now it comes with a nice sidebar Widget support to show the top ten charts for the top commenters.
<h3>Usage</h3>
When you activate the plugin it just works removing the “nofollow” attribute from your comments authors link, but if you would like have the image band at the top of your pages too, you MUST put the php function into your template file just below the attribute like this:
<pre><code><body>
<?php if (function_exists(noff())) noff(); ?>
...
</code></pre>
Remember to set the plugin option by clicking wp-admin -> options -> NOFF
