Besides having admins per forum, I assume that these admins have also less privileges on global level (non-forum related stuff).
I would think that forum-admins are allowed to
- change statuses of ideas
- add/read the notes (which are only visible to admins)
- do moderation on ideas
- batch upload ideas to their forum
While a global admin can do the setup things.
- Upload logo/custom design
- Domain aliasing
- Create/delete/edit forums and forum-settings.
