There are several plugins that will do topic moderation and inform admins of new topics.

You can start by simply using the ones in bbpress – go to

Dashboard>settings>discussion and you can set rules on who can post

Additionally there are 2 plugins that work well with bbpress :

bbPress – Moderation Tools Add the ability to moderate and approve new topics and replies in bbPress
bbPress – Notifications allows you to automatically send email notifications to specific users when new topics or replies are posted.

However the plugin in this page does one simple thing, it emails a predefined list when particular words are put in a topic or reply.

Download and set up

Simply download the plugin.

then go into Dashboard>plugins>add new>upload, and upload the zipped file, and then activate

To set up, go into Dashboard>settings>bbp Word Inform, and set up the email and choose the words you wish to be alerted to.
