 Registrations are permanent read-only copies of a project. Registrations save the state of a project at a particular point in time, such as right before data collection or right when a manuscript is submitted. Keep in mind that a registration takes the same privacy settings as the project. That is, if you register a public project, then the registration will be public as well. Before initiating a registration, make sure that the project is in the state you wish to freeze it. For instance, links will be copied into your registration but cannot be frozen. Consider turning your links into forks to freeze them. To register a project, click on registrations in the grey navigation bar. Click on new registration, select a metadata template, fill it out, and then confirm the registration. Once you've done this, your registration exists as a separate permanent URL that is linked to your project. You can then continue editing and revising the project.
