The Manage Forums Section is the administration area where you create and configure your Groups and Forums.
In Simple:Press Forum, a Group is a container of one or more Forums. There must always be at least one Group and one Forum in order for users to post Topics in your Forum. If you are just getting beginning with your Forum, you can read our Getting Started with Groups and Forums guides to help you with the basics.
This Administrative section is where you create the groups and forums, manage or edit them as needed and merge forums.
This is also where you would add global or delete a whole permission set and manage the Global RSS settings.
