This plugin is for bbPress 2.x
Many people who run forums would like to know when a new topic (thread) has been posted but do not have the time to constantly check their forum for activity. This solves that!
This plugin will send an e-mail notification to specific addresses when a new topic has been posted. The users who receive notification along with a simple e-mail template is configured in the bbPress settings.

Email notifications sent by bbPress will sometimes include unwanted HTML entities, particularly in the email subject but sometimes in the email text as well.
For example, a forum topic as follows:
<pre><code> My thoughts & objections
</code></pre>
might come through with an email subject as follows:
<pre><code> My thoughts &amp; objections
</code></pre>
There is a fix for this marked “under consideration” in the bbPress bug tracking system: 
<a href="https://bbpress.trac.wordpress.org/ticket/2865" rel="nofollow ugc">https://bbpress.trac.wordpress.org/ticket/2865</a>
In the meantime, this plugin implements a version of the suggested fix. (Props to @thebrandonallen for the patch code.)
IMPORTANT NOTES:
This plugin only works with bbPress 2.5.8 or later.
If you’re using other plugins that affect how bbPress sends emails, then this plugin may not solve your HTML entities issues.
