We use a number of agencies and have local user logins created for their employees. They often come and go and it would be helpful to have a Note field on users record so information can be recorded like - who within our company is responsible for the user, what job function they serve, etc.

Would also be good to have an expiry field so that the users would expire - with a notification warning that the expiry is coming up to avoid having old users hanging around with access to our system,
