pne | The long-dead zombie rises again: birthday notifications

There is (or was?) an option on people's Edit Profile page to select birthday notifications, but the feature has been disabled for as long as I can remember (due to the load this placed on servers, or the volume of email this caused to be sent, or something).

However, this feature is apparently scheduled to return in the next release (r7, codename "Hamster").

Edit: oh, and it's even mentioned in news! (And they say: "Comment if you remember birthday notifications, because that means you're old skool.")
