I'm able to import calendar meetings with attendees (both from the Preferences part of the GUI and using curl). But the events don't show up on the attendees calendar until I hit Send in each event detail page and they acknowledge it. Is there some way to automate that (sending invite emails)? The above talks about "send emails ... with a script". How can we do that?

Even better, is there some way to import group events (those with attendees) that automatically puts the events on the attendees' calendars without any user action? We want this to migrate calendar data from our existing system (webcalendar).
