Question 1: I am going to post this screenshot of the staff rank layout. In the layout I need it that "person a" cannot jump from "Support" to "Moderator" and from say "Senior Administrator" to "Head Administrator" etc. Although I need it that "Head Moderator" can add and remove people from "Moderator" and "Support". I also need it that only "Head Administrator" can assign and remove all staff ranks beneath it.
*Note: "Founder" and "Community Manager" have powers of essentially 75 for everything already.

Question 2: Currently when people have the "IG Member" group they can assign them self "Channel groups", can someone tell me how to stop them from doing so?
*Note: IG Member was based off from a "guest" group.

Thank you to those who assist me
