You should be able to remove yourself or personally archive projects that you are no longer working on in ACC Build. I work on a lot of projects and it is difficult to stay organized when I can't remove myself after a project is complete for me. I rarely stay to the end of a project and have more involvement upfront, so waiting until a project admin archives the project is not feasible. Without the admin archiving the project, there are a lot of times that I cannot even stop notifications without contacting the admin for the project.
