The Exchange bbPress Membership Add-on adds membership management functionality into your bbPress forums.
In your forums, topics and replies, you can now restrict access based on membership. To add a restriction, navigate to the Membership Access panel and click the Add Restriction button. Here you can select the membership that you want to have access to this forum and determine when they can have access to this forum.
When you’re done, simply click the Ok button and update or publish your forum, topic or reply.
You can also add these restrictions to bbPress from your membership products. Click the Add New Rule button and now you can select your forums, topics, replies and even topic tags.
Once you’ve selected your content type, you can select the specific content you want restricted, and again, set when this would become available.
Once you’ve finished adding in your new rules, you’ll simply update or publish your product.
