Trouble is, the system expects you to comply with 48 hours notice for these events, and it nags you about posting minutes, even though there will never be any!
So there is a new option when you schedule a meeting, or when you set up a regularly scheduled meeting. You can indicated that it is an "Event not Subject to Open Meeting laws". These events will appear in italics in the calendar view, and they will not expect you to post or record minutes. They also don't enforce the 48 hours notice requirement.
