As for ROs: I became this room's owner by default as the most talkative person after the previous RO was absent for many months, that's an automagic process. After a while I started to feel like being the sole RO was influencing my interactions with the room in a bad way and the elected mods weren't sufficient to mitigate that only-me-ness, partly because of time zones.
So I consulted with the mods to identify people we thought would be good additions to an RO team so none of us would have full responsibility and we could check in on each other.
