Maybe, For One Birthday...

I have several birthdays to track. They are all recorded in my contacts. All I ask is that they let me know a few days before, so I can greet them appropriately on their special day. I do NOT want to put them in by hand. However, notwithstanding the fact that it indicates it can do what I want,you will end up with your Contact List ticking off the contacts you want added. More seriously, after you click on a contact you end up flipped to a screen where you have to enter the birthday all over again. At that point I said enough is enough. If they had let me tick off my contacts manually in batch mode, I might have given three stars. If they read them all in, five stars. As it is, one star is more than generous!
