Howdy Great Taste,
Good question. Those events will not be imported as recurring events. The recurring rules proved too complicated to be able to import via CSV. The only way to setup recurring rules is manually. You could import the first event in the series, then edit it to add the recurrence rule.
I wish I had better news here. We are hoping to add recurrence support to our iCal importer, but even that format has proved hard to adapt the recurring rules for.
Does that answer your questions?
Cheers!
