Okay, I've subscribed to a couple of calendars in iCal, including birthdays from Address Book, but I'm completely stumped. If I want to receive an alert when one of these items is coming up, then what do I do? I don't want to rely on alerts being added at to the subscription itself, I want to be able to customise on my end when I get an alert for an entry, and when or what that alert will be. Is this possible? I don't see any options for it. If not, anyone know of any good alternative calendar applications that are like iCal?
