Hi, Maddy. I had a difficult time figuring out where to compile groups/orca, also. It isn't located in your admin panel, but you do have to be logged in as the admin.
Type http://yoursite.com/groups/orca, or if that doesn't work http://yoursite.com/groups/orca/#group/.htm
You'll see Forum Index (reported posts| compile language: en).
