Once you find the Project you'd like to adjust, click View Project.
Once you've clicked on the View Project button, you'll see a Delete option in the upper right hand corner. Click this link.
Read the disclaimer, if you'd still like to delete the Project, click Yes, I understand - Delete this project.
