Rename roles
The name CREATOR
is imprecise because rooms can be transferred to a
new owner which does not change the actual creator.
The name EXECUTIVE_MODERATOR
is unnecessarily verbose since there
there are no different moderator roles anymore.
New role names:
-
CREATOR
=>OWNER
-
EXECUTIVE_MODERATOR
=>MODERATOR
