I have found a little bit about public and private calendar, but I was hoping for a little more.

Is it possible (preferably simple) to have multiple calendars displayed at the at the same time. Possibly in two separate content island box thingys? I have an idea that would require one calendar with data that can only be put in by the administrator but read by all. And I would want a second calendar where any member can put in data that can be read by any other member.

If it sounds like I don't know what I am talking about, it's true. I am on UBB Classic now and don't have Threads just yet, but it's on order.
