This plugin extends the comment closing functionality in WordPress to allow 
you to extend the discussion time when older posts have recent comments 
accepted, or to override the comment closing time on a post by post basis.
Note: PHP 4 is no longer supported. As of version 2.1, Comment Timeout requires PHP 5.2 or later. 
If you are still using PHP 4, you should use Comment Timeout 2.0.1.
<h3>Configuration</h3>
You can change various settings globally on the “Comment Timeout” page under the 
“Options” tab on the WordPress dashboard. Most of the options are fairly 
self-explanatory.
You can also change options on a per-post basis by looking for the 
“Comment Timeout” section in the sidebar of the post or page editor.
<h3>Template tags</h3>
Comment Timeout 2.1 introduces two new functions that you can use in your theme:
<pre><code>get_comment_timeout()
</code></pre>
Returns the UTC time, as a Unix timestamp, when comments will be closed for the current post.
<pre><code>the_comment_timeout($relative, $dateformat, $before, $after, $moderated)
</code></pre>
Formats and displays the date and time after which comments will no longer be 
accepted on this post. Parameters are:
<ul>
<li>$relative: Set this to <code>true</code> if you want to display the date in terms of the time remaining 
(for instance “in 3 weeks”). Set it to <code>false</code> to display it as an absolute date.</li>
<li>$dateformat: The format in which the date should be displayed, as used by the PHP 
date() function. If you set this to <code>false</code>, it will use the date format that you have configured 
globally for your WordPress installation.
<ul>
<li>If <code>$relative</code> is set to <code>true</code>, this parameter is ignored.</li>
</ul>
</li>
<li>$before: The HTML to insert before the date that comments will be closed.</li>
<li>$after: The HTML to insert after the date that comments will be closed.</li>
<li>$moderated: The HTML to display when late comments are being sent to the moderation queue 
rather than being rejected outright.</li>
</ul>

Comment Timeout

Closes comments on blog entries after a user-configurable period of time, with an option to make allowances for active discussions.

This plugin has two modes – basic and Akismet-enhanced.
Basic mode: the plugin will serve a CAPTCHA to all commenters that aren’t logged in and don’t have a previously approved comment. Repeat commenters will never see a CAPTCHA.
Akismet-enhanced mode (recommended): the plugin will serve a CAPTCHA only if Akismet identifies a comment as spam (much less frequently than the basic mode). Just install an activate <a href="https://wordpress.org/extend/plugins/akismet/" rel="ugc">Akismet</a> to enable this mode.
Note that a CAPTCHA will only appear after a comment is submitted. When a commenter is served a CAPTCHA:
<ul>
<li>If they fail, then the comment will be automatically discarded or trashed (and won’t clutter up your spam queue).</li>
<li>If they pass, it will be allowed into the spam queue (or approved, if you so choose). This means that any false positives from Akismet will be easily identified without you having to trawl through all the spam comments manually.</li>
</ul>
Most genuine commenters will be able to comment on your site hassle-free, without ever seeing a CAPTCHA.
The default CAPTCHA is a simple text-based test. There is also the option to use <a href="http://www.google.com/recaptcha" rel="nofollow ugc">reCAPTCHA</a> if you want something more robust (free API key required). You can also style the CAPTCHA page to fit with your own WordPress theme.
If you come across any bugs or have suggestions, please use the plugin support forum or <a href="http://rayofsolaris.net/contact/" rel="nofollow ugc">email me</a>. I can’t fix it if I don’t know it’s broken! Please check the <a href="https://wordpress.org/extend/plugins/wp-conditional-captcha/faq/" rel="ugc">FAQs</a> for common issues.
