I've known Ivy for close to two decades now, we've co-sysadmined things previously and I vouch that you can trust her as you trust me.
Ivy will have access to all the backend systems and accounts, not to run things on a daily basis, but to ensure continuity of service if I can't.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
