How to Use Calendar Groups with the New MobileMe Calendar

I have more than 25 business calendars in iCal, divided into five calendar groups. I use MobileMe to keep them in sync between all of my Macs, but I just upgraded to the new MobileMe Calendar and now all of my calendar groups are gone!
We highly recommend that all MobileMe users upgrade to the new MobileMe calendar (me.com/calendar) because it finally provides reliable calendar syncing. All of your calendar data now resides on MobileMe’s new CalDAV server, and your client devices (Macs, iPhones, and iPads) simply sync with the CalDAV server.

BusyCal can bring back your calendar groups to MobileMe-hosted calendars or any other CalDAV-hosted calendars.
However, the downside to this is that CalDAV does not provide support for calendar groups, so all of your calendars are placed into one “flat list.” This makes it difficult for someone like yourself to quickly switch between viewing different subsets of calendars.
iCal can’t solve this problem, but Mac|Life Editors’ Choice winner BusyCal ($49, busymac.com) can. BusyCal lets you create calendar groups for any calendars hosted on a CalDAV server. There are a few minor caveats since you’re dealing with limitations of the CalDAV protocol. Your calendar groups will stay local to each Mac, so you’ll have to create and manage your calendar groups locally on each Mac. Plus, your calendar groups will not sync to the MobileMe website or your iOS devices.
