Tracking Birthdays

In the past, I've kept track of birthdays on my friendslist via my "My LJ" page, but apparently that information has disappeared. (I suppose it's possible that all of my Friends simultaneously blocked access to their birthdays, but it seems unlikely.)

Does anyone know of another way (besides the obvious check-'em-all method) of tracking FL birthdays?

Apropos of the previous post: happy birthday, toraks!
