Add a friend
Find someone by name or username in Friends, or from their profile, and choose Add friend. They get a request; once they accept, you are friends. You can withdraw a request or remove a friend at any time, and they are not told.
Your home feed
Your home page shows what friends and fellow space members did lately: what they rated, added, finished or wrote. It only ever shows what they chose to share with you.

React
Answer a friend's rating or note with a reaction — agree, love, curious, surprised or funny. They are told about your first reaction. Curious about what they rated? Add it to your own plans from there.
Profiles
A profile shows someone's categories, collections and latest ratings — only the ones you are allowed to see — and the favourites they pinned. You can pin up to four topics you rated to your own profile.
