Yes, it is possible to delete a landing page or widget project.
You are able to edit any of the content of a project before or after it is launched, or change the project type from widget to landing page (and vice versa) so you don't need to delete a project
If you would like to delete a project:
- select My Projects from the project menu
- locate the project you want to delete
- click the X in the upper right hand corner of the project
- NOTE: deleting a project is permanent and cannot be undone
