What does pending mean?
When an event is Pending it means that the event has not yet been accepted by the calendar
moderator. This has several consequences. 1) Until the event is approved or rejected only the moderator will be able to view the event's details. 2) Only the
moderator has the authority to accept or reject the event.
If the moderator accepts the event, then other subscribers to the calendar will
also see the event; but if the moderator rejects the event then it
will be deleted. The moderator also has the option to send an email containing an explanation of why the event was rejected.
