Membership groups control access and permissions within a forum.
People start with no permission to do anything, and are granted permission by being a member of a membership group.
The vast majority of people are either guests (not signed-in) or members (signed-in).
The default groups are site-wide, and all new forums have these groups. If a forum has it's own custom membership groups, then these may override the defaults and allow for private forums.
