What I'm trying to do is allow registered users to create a list of gift items they would like for Christmas. So I've created a custom post type called 'gift' and a custom taxonomy of 'list' but I can't figure out how to relate the 'list' to the user. I would like to allow users to create multiple lists, but I can see a problem where 2 users may create the same list name and therefore causing headaches on which list belongs to who.
Have I set this up the right way? What would you do differently?
