Inspired by comment 23 on trac ticket <a href="https://core.trac.wordpress.org/ticket/27111#comment:23" rel="nofollow ugc">#27111</a> this plugin allows you to globally toggle comment functionality across your WordPress installation including:
<ul>
<li>Disable support for comments and trackbacks in post types </li>
<li>Close comments on the front-end </li>
<li>Hide existing comments </li>
<li>Remove the admin comments page and comments menu </li>
<li>Redirect any user trying to access the admin comments page </li>
<li>Remove comments metaboxes from the admin dashboard </li>
<li>Remove comments links from the admin bar</li>
</ul>
