Released 31st March 2018 on WordPress.org as a free extension for the TwitchPress system. This is despite my original plan to make it the first premium extension. The change of plan was due to some funding by the community.
The initial features offered by TwitchPress Subscriber Management are tables that allow us to view Twitch subscriber related data. This requires subscription syncing to be active. We can see a list of subscribers and recent subscription changes.
Download and Repositories
Live websites should always use the official WordPress.org repository to update the TwitchPress Subscriber Management extension. View the plugins profile here but install the plugin in your WP administration area.
