Changing cmdpermissions

Hi, ive got a question for the admin. Admin, could you please change some commands? I really like doors and air_switch so it would be nice if you could change all doors to guardian . It also would be very kind from you if you could change /setrank ( /rank ) and /promote ( /pr ) to Developer. I don't really like it to be able to rank because a lot of people are ugly to me and are upset and say things like: "I hate you!" to me, also if they are my friends, just because I don't wanna rank them. And please also change /save to Guardian i promise i wont abuse it, i just want it to safe our new map (where starting it again, I hope).
