How to copy calendar subscription events to another iCal calendar?
I subscribe to TripIt subscription feeds to my iCal. I want ability to copy events into separate calendar I use for work (for sharing w/ officemates via Outlook Exchange server). But events created by the subscriptions do not allow reassigning calendar. In other cases like this, I right click on event and "duplicate" to create an event copy that allows assignment of calendar. But these subscription feeds do not seem to allow duplication.
What to do?
