To delete an existing Space, click on its name from the Resources page.
Hover over the Tools dropdown menu and click Delete Space.
A popup will open prompting you to confirm whether you want to delete the Space and all Pages within it. If you are happy to proceed, click Confirm.
Note: if you delete a Space which contains file attachments, the attachments will be deleted too. It will not be possible to restore either the Space, the Pages within it or the attachments.
