How it works
In the WordPress Discussion Settings, there is an option called “Automatically close comments on posts older than” whatever specified number of days. When this setting is enabled, comments will be disabled on any posts that are past the deadline, whatever “x” number of days.
What WordPress is missing is a simple way to override that global option on a per-post basis. That’s exactly what this plugin does.
For any post that is past the comment deadline, this plugin will display a small meta box on the “Edit Post” screen for each post. There you can check the box to enable comments on the post. Comments will then remain open for that post indefinitely, until the box is unchecked or the plugin is uninstalled. Check out the screenshot below to get a better idea.

BuddyPress First Letter Avatar sets custom avatars for users without profile picture or Gravatar. The avatar will be a first letter of user’s name. You can also configure plugin to use any other letter to set custom avatar.
BuddyPress First Letter Avatar is based on my other plugin – <a href="https://wordpress.org/plugins/wp-first-letter-avatar/" rel="ugc">WP First Letter Avatar</a>. BuddyPress First Letter Avatar is basically the same thing, but programmed to work with BuddyPress.
BuddyPress First Letter Avatar includes a set of beautiful, colorful letter avatars in many sizes. Optimal size will be chosen by the plugin in order to display high quality avatar and not download, for example, big 512px avatars when only 48px is needed… PSD template for avatar is also included.
You can also create your own avatar set by creating new directory next to ‘default’ folder and following the naming convention from ‘default’.
By default, custom avatar will be set only to users without profile pictures and Gravatars, but you can change that in settings and not use Gravatar/profile pictures at all.
BuddyPress First Letter Avatar helps you bring more colors into your BuddyPress site. Plus, your users will be more willing to actively participate in your site since they can actually relate to these avatars much better than to the Mystery Person.
All images were compressed using the fantastic <a href="https://tinypng.com/" rel="nofollow ugc">TinyPNG</a>, so avatars are incredibly light and ultra-high quality.
Plugin is also available <a href="https://github.com/Dev49net/buddypress-first-letter-avatar" rel="nofollow ugc">on GitHub</a>.
<h4>Requirements</h4>
BuddyPress First Letter Avatar requires at least PHP 5.4. It does not work properly on PHP 5.3.x and earlier.
