The CCSESA Forum uses a popular, lightweight, easy to use forum plugin called bbPress. I have initially created 8 forums for the top committees. Each forum has the ability to be limited to certain access levels. To manage these access levels and create more forums navigate to Forums > All Forums.
Here you can add a description to your forum and most importantly manage who has access by checking the appropriate boxes under WordPress access control. Click Publish to save your changes.
