Like the rest of incubation, graduation is a process. Updating your status records as you progress will enable others to assist.
Update the podling status page. All sections should now be filled in including EXIT. Take some time to read carefully since this page forms the final public record for graduation.
Update the Incubator status page to denote the project as "graduating" when you commence, then as "graduated" when you are finished. The notes below will assist.
