first off, trakt is only used to manage whay shows and movies you watch. it has nothing to do with actually watching anything.
secondly, you can create, manage, and like other users’ lists if that is what you’re asking about.
you can read up on this topic that the trakt staff put together:
To view these lists in say in kodi, you’d need to install some sort of addon that allows you to see these trakt lists. I don’t particularily use kodi, so i can’t say much about it. for kodi addons, you probably need to ask elsewhere as this is only trakt related.
hope that helps.
