For whatever reason, I can only choose my .Mac email (Home) for iCal to email me as a notification. I already added my work email address to my info in Address Book, anything I can do? Thanks
No it really should work. I do it all of the time. I set reminders to clients and everything. They really think I am cooler than I really am.
You probably only have your .mac account in your address book. First quit iCal. Then, go to address book, double click your name (computer user) and select "edit." Add the email you want to have the alarm sent to and save. Reopen iCal and try setting the alarm again - your new email will appear. EDIT: Oh, i see you did that already. Are you sure you added your work email to your personal user account in address book?
