To help you manage your collection, we display collections under two areas: current and archived. Archiving a collection is useful if you are not currently working with the collection. You can choose to archive the collection only, or the collection and all the proofs inside of the collection that you own.
To archive a proof collection
Open the manage collection pane either by:
Clicking the collection icon on the proof tile, or
Clicking the collection icon when viewing the proof, then clicking the cog icon at the bottom right of the collection screen, or
On the dashboard side panel, clicking the cog icon to the right of the collection name.
Select archive collection and confirm whether you’d like to archive the collection only, or proofs you own as well, by clicking the collection & proofs or collection only button.
