Manifold currently offers two options for displaying texts--draft mode or public mode. Draft mode will hide your project from public access. This may be a good option for class or student projects. Always consider UCLA’s Student Collaborators Bill of Rights, “8. When digital humanities projects are required for course credit, instructors should recognize that students may have good reasons not to engage in public-facing scholarship, or may not want their names made public, and should offer students the option of alternative assignments” when incorporating digital scholarship tools into a course.
Draft and public modes are controlled in the Visibility section of the General category of creating a project in the Manifold User Guide.
