> how do I let other people add things to my list? You need to utilize the Invite feature located at the top of your list page. Its a standard collaboration tool that many people overlook. When you click Invite, you are presented with two distinct settings: View Only or View and Edit. For a baby shower where you want your family to contribute, you have to select View and Edit. Once you generate that specific link, you send it to your mom and aunt. After they accept the invitation, the list becomes a shared space. Anyone with those permissions can add or remove items, which effectively eliminates the risk of buying doubles. Based on my experience managing group registries, this is the most reliable method for keeping everything organized. Just ensure they are logged into their own accounts when they click the link so Amazon recognizes them as collaborators.
