As per the README, in the Configuration section:

For forum and usergroup permissions, forum rating follows the existing "Allow thread rating" options. So if thread rating is enabled for a forum, the forum itself can be rated, subject to the usergroup settings. Usergroups who can't rate threads in a given forum won't be able to rate the forum itself either. Everyone can see current rating values for ratable forums.

And in the To Do section:

1) Add separate forum rating permissions, rather than inheriting thread rating permissions. The reason I didn't do this to start with is I'm still looking for an upgrade safe way of adding forum permissions.
