To facilitate your sleuthing capabilities, I offer up this quick little OT tutorial. All JMO IMHO.
In Amazon, under Accounts & Lists, click on Wishlist. Wishlist-Default list (And Shopping List, if you have one) show up. Either marked Public, or Private. Click on the list you want to look at. Wishlist-Default should already be highlighted. On the side should be a "More" button. Clicking on that gives you Manage List, and Print List. Clicking on Manage List opens up that list. Here you can choose Public/Private (and a couple other settings), as well as Delete List at the bottom. Clicking on Save Changes updates your preferences. Clicking Cancel negates any changes.
