Reactions and comments: how do they work?

Public collections and pieces are social — you can react to them and leave comments, just like you'd hope in a collector community.

• Reactions are a quick way to show appreciation for a great piece or a well-documented collection.
• Comments let you ask questions, share knowledge ("I have the same one — watch the front coupler"), or just say nice things.

Reactions and comments appear on public items only. If you'd rather not receive them, you can keep items private — see What's the difference between a public and private profile?. You'll be notified when someone reacts to or comments on your collection.

Be kind and constructive — this is a small, friendly community.
