Sometimes there's a topic you want to revisit- or a project!
To re-open your project:
Go to the project you want to re-activate.
In the top left of the project page, click the Edit icon below 'Description'.
On the Edit Project page toggle the lock icon to move between open and closed state.
Select Close to confirm your changes.
❗ Don't forget! - you can still access closed projects on the Projects page. Just update your Project Statuses view to closed to see your closed projects.
