Surely, you have many e-mail contacts. Ones are friends, others are colleagues, and someone is your distant relative. Probably, you want to differentiate them from each other. It’s possible.
Once signed up, you can create different wishlists for different groups i.e. friends, family, colleagues etc. Each wishlist will be visible only for the chosen group. Besides you can create the general wishlist for all of the groups.
There is also simplified design for kids who want to inform parents about their wishes. Let your child or friends’ children create their own wishlists.
