Link aMember to different WordPress blogs
To add aMember users to more than one WordPress blog, create a separate instance of the WordPress protection plugin for each blog. Before continuing, enable and configure the WordPress plugin for the first blog.
Navigate to aMember CP -> Configuration -> Add-ons.

On the My Plugins tab, switch the status filter to Active and confirm that WordPress is enabled.

Scroll to the bottom of the page and click the Create new plugin instance clone icon.

Select WordPress and click Create New Instance.

Open the settings for the new WordPress:1 instance. Set WordPress Folder to the installation folder of the second blog and complete the remaining WordPress settings. Configure product integration rules for the new instance as needed.
