replyPUSH

<p>Much like WordPress.com’s “Comment Reply via Email”, you can reply to any post you subscribe to.</p>
<p>Integrates with the wonderful <a href="https://wordpress.org/plugins/subscribe2/" title="subscribe2" rel="ugc">subscribe2</a> and <a href="http://replypush.com" title="replyPUSH.com" rel="nofollow ugc">replyPUSH.com</a> service to provide the email reply magic.</p>
<p>It automatically adds notifications for comment posts to keep the conversation flowing 🙂</p>
<p>All the subscriber need do, is reply at the top of their quoted email notification.</p>


Reply By Email

Allows your users to reply to articles / blog posts and comments via email.

<p>Shortnotes adds a custom post type, <strong>Notes</strong>, used to publish short pieces of content on your website, similar to social networks like Mastodon, Twitter, or Instagram.</p>
<h3>No titles</h3>
<p>The <strong>Notes</strong> post type does not support traditional titles.</p>
<p>Note titles are <strong>not</strong> generally meant to be displayed as part of the theme layout. You will likely need to adjust the look and feel of your theme accordingly. See the Theme Customization section below for more details.</p>
<p>A title <strong>is</strong> generated automatically from note content and is used as the note’s document title. This is readable by search engines and displayed in browser tabs.</p>
<h3>Limited blocks</h3>
<p>The <strong>Notes</strong> post type supports basic content blocks like paragraph, list, quote, image, preformatted text, gallery, video, and embed. Using a defined list of relatively simple blocks helps to keep notes simple.</p>
<h3>Webmention support</h3>
<p>The <strong>Notes</strong> post type includes support for the <a href="https://wordpress.org/plugins/webmention/" rel="ugc">Webmention</a> and <a href="https://wordpress.org/plugins/semantic-linkbacks/" rel="ugc">Semantic-Linkbacks</a> plugins.</p>
<p>URLs in note content are processed as possible <a href="https://indieweb.org/webmention" rel="nofollow ugc">webmentions</a>.</p>
<p>A panel in the block editor allows for the addition of a reply to URL and name. When entered, they are used to provide markup for a semantic webmention <a href="https://indieweb.org/reply" rel="nofollow ugc">reply</a>.</p>
<h4>Reply to template tag</h4>
<p>The <a href="https://indieweb.org/reply" rel="nofollow ugc">reply</a> specification works best when the <code>u-in-reply-to</code> element is outside of the <a href="http://microformats.org/wiki/h-entry#Properties" rel="nofollow ugc">main content element</a>, defined by <code>e-content</code>.</p>
<p>A template tag is provided as part of the Shortnotes plugin that can be used to output reply to markup in your theme.</p>
<pre><code><article class="h-entry">
    <?php
    if ( function_exists( 'ShortNotes\PostType\Note\reply_to_markup' ) ) {
        \ShortNotes\PostType\Note\reply_to_markup();
    }
    ?>
    <div class="entry-content e-content">
        <?php the_content(); ?>
    </div>
</article>
</code></pre>
<p>If this template tag is <strong>not</strong> used, then the Shortnotes plugin will automatically prepend the reply to markup to <code>the_content</code>.</p>
<h3>Theme Customization</h3>
<p>No customization of your theme is required to use this plugin, though you will likely want to think through how titles are displayed and if you want full support for webmentions.</p>
<p>If you do find yourself wanting to customize, I have made <a href="https://github.com/jeremyfelt/writemore/" rel="nofollow ugc">my site’s theme</a> fully compatible while developing this plugin. It may be a helpful example.</p>

I love these indieweb type plugins, especially where hey break out indieweb types into their own cpt, this is a much better approach of using post for everything

Great plugin

Add a notes post type to WordPress. For your short notes.
