Discourse is a fantastic new forum that can add another layer to your WordPress community. This plugin allows you to create a fluid experience by using your WordPress installation as the authentication server, creating a single-sign-on (SSO) for your users! Notes: The Discourse option “Staff must approve all new user accounts before they are allowed to access the site.” needs to be disabled for this to work properly. Some Features: Seamless integration into almost any WordPress installation. Get setup within minutes through 3 easy steps. Anyone can do it. Coming Soon: Only allow access with certain capabilities or roles.
