I've been using the "cupcake" sticker for close friends' birthdays so I can tell the difference between close friends and "Facebook" friends as a better reminder, since the sticker pops out at you more. I was thinking it would be a good idea if you were able to attach the sticker to all future birthdays, or all future events, this way you don't have to keep putting a sticker up for reoccurring events and birthdays every year.
