Im thinking operator as in like builder, Mod, Designer, Operator, Admin, and Owner I hope this gives some ideas for the admin, owner, ect
I agree with laser, isn't the only difference between mods and admins is /gamemode and /tp? Operator wouldn't really have any perks a mod doesn't have.
Anyway why is sonic interested? It's not like he's gonna become mod or anything by suggesting a rank for the staffs buisness, plus, there lots of ranks. (P.S: what does builder give you except for helping build the server?) @Claud
You don't have banning, kicking or muting abilites, apart from that I don't know much. Maybe ask a builder?
