You cannot undo deletion of a Project.
To delete a Project, navigate to the homepage by clicking the Gridfox icon in the top left of the screen or by using the Back to Projects link.
Open the Project menu and select the Delete Project. Read through the warning message then confirm the action by clicking the Delete button.
