Cool iCal feature - multiple alarms

Have you ever wanted iCal to email you about an event a week in advance and beep at you 15 minutes before it happens? Well, wait no further. It turns out that the software allows multiple alarms for the same event. After setting up the first alarm, just click on the Alarm label to the left of the first alarm and it will pop up a menu that lets you add another alarm or remove that one. Very nice.
