That’s bbPress, not Multisite.
Okay, so are they basically the same? If not, which is higher ranked?
I’d like to know, so I don’t add someone to the wrong group… 🙂
No, I didn’t say they were the same. The roles like ‘Keymaster’ are generated by bbPress, not Multisite. You need to read the bbPress documentation to understand what Keymaster is 🙂
Administrator: Default WordPress role, has full admin access over a site.
KeyMaster: Created by bbPress. Can create, edit and delete other users’ forums, topics and replies. Can manage Tags, and moderate a forum with the moderation tools.
