Add members only bbPress forums, topics & replies
The bbPress Membership Add-on for Exchange adds the ability to enable membership functionality for the bbPress plugin, the free forum software that allows you to set up discussion forums inside your WordPress site.
With this Exchange add-on, you can restrict bbPress forums, topics and replies to require certain membership levels sold in your Exchange powered store. Once you set up these membership access restrictions, a user will have to have purchased a certain membership product to have access to the forum, topic or reply.
