A customer had the following question on CAC:

Hey, is it necessary to have a login in order to insert someone's vacation into the calendar? for example we have three users, Peter, Max and Jane and only Peter and Jane have a login. Is it possible for Peter to insert Max'es vacation into the calendar so that this inserted vacation does not appear to Jane as Peter's vacation?

If you could add users to a people calendar via email, you'd be able to add someone to a people calendar without them being a user of the system.

It could also be a good way to spread Confluence to potential new users
