I manually edited the URL of the external link (per Giving Credit (for links) where credit is due - #2 by DanRathbun), so credit will go to the finder. (I hope.)
I would hope that individual powers could be toggled.
The Sage group was a special “semi-moderator” addition, whose trust level were set to static. (They do not have to maintain a certain number of posts or reads per day, etc. Their status is static compared to normal users, who’s trust level will decay with nonuse.)
So because they are a special state, I’d hope certain powers can be granted on a power by power basis.
