replyPUSH

Much like WordPress.com’s “Comment Reply via Email”, you can reply to any post you subscribe to.
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.
It automatically adds notifications for comment posts to keep the conversation flowing 🙂
All the subscriber need do, is reply at the top of their quoted email notification.

Reply By Email

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

Give your bbPress forum users the ability to report inappropriate content or spam in topics or replies. This plugin adds a “report” admin link to topics and replies, when clicked, the topic/reply is assigned a post status of “User Reported”.
All logged-in users can report content and see that a topic has been reported, only Moderators and up can un-report the content. Integrates with the standard Topic admin screens.
When a topic is reported, a banner is shown at the top of the page indicating that the topic has been reported as inappropriate. For replies, a message is added within the reply, before the content.
Requires bbPress 2.4+.
