Permanently delete your published project from the Lulu server only if it has not been purchased. If someone (including you) bought a copy, the project must be "Retired" rather than deleted.
To delete your project: From your Project List, click the Delete icon next to the project you want to remove. Confirm the deletion.
To retire your project: From your Project List, click the Revise icon next to the project you want to remove. Scroll to the Availability/Project Status and click the Retire link.
To view retired projects, click the Show retired projects button at the top of the Project list in the My Projects section of your My Lulu tab.
