How can I close, extend, or temporarily suspend a project?

You can do this if you are the project leader or Researcher+ with this authority. Log in to the CBS microdata portal and go to "My Projects." Select the project for which you want to change the status. Click on the "Change Project Status" button on the right side under Change", choose to "End Project," "Extend Project," or "Temporarily Freeze Project," and click "Create" at the bottom to save the change.
