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+.

This was built out of a need for a way to bring registered users into a conversation unfolding in comments on posts. I work with an art collective and we’re all posting multiple posts on multiple topics and as we’ve tried to shift more and more of our conversations out of email and onto our website, there didn’t seem to be an easy way to bring specific people into these comment conversations without using a more general comment notification plugin. Notify Tagged User attempts to change that.
This plugin would help out any multi author blogs, and in particular, teams or project blogs that focus on internal communication.
Basically the plugin works by using the familiar Twitter @user reply syntax in the following way:

-if a registered user’s nickname is found, get the associated email address 
-send an email to all users tagged asking them to join in on the conversation
