I need one as well.
We used to be able to create and share the wish list but now I can't see to figure out how to use that. I can't understand why they don't have one. I have been asking for one for over 5 years.
There is a wishlist, but not sharable nor searchable. People have been using Amazon to create a wishlist -- that drives customers away.
Come on ... there is on the back end https ... admin/customers/2095177
Why not put just simply admin/wishlist/2095177 --- you're pulling an array to create that. Just pull it out. Come on!
Can you add buttons to at least allow users to email their wishlists to others?
