I've talked to Megiddo about this, and he seems fine with it, so we will be adding this feature (time permitted). I need to get an issue created on our issues page as well, but.. for now just know that it's on our radar!
The eventual echo modes will end up something like this:
; Echo modes:
; 0 - OFF No output to any players when an admin command is used
; 1 - ADMINS Output to admins only.
; 2 - ANONYMOUS Output to players without access to see who used the command (admins by default) similar to "(Someone) slapped Bob with 0 damage"
; 3 - FULL Output to players similar to "Foo slapped Bob with 0 damage"
