AFAIK:

-Jay / Admin
-Wook / Mod
-Anchor / Mod
-Mothr / Mod
-Zion (still active?) / Mod

I think that’s the list.

At FE we have a handy page for this sort of thing.

And a color scheme (JEDIT: which doesn’t show up here).

Usergroup Legend
Administrator, Super Moderator, Staff Writer, Faneditor, Academy, Cover Artist, Donor/Sponsor, Registered User, Banned User

JEDIT 2: No idea why we listed “Super Moderator” other than to further inflate my ego.
