Hello, I've successfully set up a calendar server on my Linux machine, and (I think) figured out how to make collaborative calendars--namely, to use the /principals/groups/users/ URL and stick with group calendars. I've converted my existing calendars by exporting ICS files and importing into my WebDAV calendars. The trouble is, suddenly attendees and locations don't behave as they do for local calendars. The app harasses me endlessly about their being "invalid." I just want plain-old informational stuff in those fields; I'm not using iCal to resolve room conflicts or anything like that. Is there a way to configure the calendar server and/or iCal to get this behavior back? The nagging is already driving me nuts. Thanks!
