In order to invite friends and family to collaborate on a collection you must first become friends with them. You can send a friend request by searching for your friend or family member using the search icon at the top of the app and selecting the “People” tab. Find your friend in the search results to follow them. They will then appear as a possible collaborator in the collaborators section of the collection.
Any user on Prepear can navigate to your profile, click on recipes, and see your collections, as long as their user status matches your profile privacy. I.E. if your profile privacy is set to “Public” any user will be able to see your collections, if your profile privacy is set to “Just Friends” only your friends on Prepear will be able to see it.
