+#### Anonymous Collections
+
+Users can create and work with collections without being authenticated to the system. Such collections (which I dub "anonymous collections") are ephemeral. They were linked to the session[2] via an anonymous user_id.
+
+In the older system, a user was able to import such anonymous collections by selecting "Import existing collections" when they logged in (see the `import_traits_to_user` function in the sessions[2] module). We need to maintain this feature. This will probably require reworking the code, to get rid of the sessions[2] module while retaining most of what it does.
