How to Set FC Chest Permissions

[Jojoya]

Also, it's very important that you do not assign the Promotion/Demotion privilege to anyone else. At all. The Promotion/Demotion privilege has the known effect of allowing people to overpromote, which would render rank-based limitations on chest, membership, and housing access pointless.

Not to mention promoting someone else to FC leader even though the person doing the promoting is a lower rank. It's one of the things SE supposedly is working to change but we haven't been given any update on progress since they said they're reviewing how FC permissions work.
