[CalendarServer-users] Adding users

So, I just followed the instructions for installing the Calendar Server on my MacBook, got it up and running, logged in as admin, and… Not sure how to add users. I tried adding another user in /conf/accounts.xml, but unless I missed something it didn't seem to create any directories for that user, even after I restarted the server. (So I changed it back.) Is this documented anywhere? I spent the last 45 minutes looking around online with no luck. :/ -- Tony
