How do I make sure my colleagues have access to the applications?

Click on “Edit page content” in your admin dashboard and navigate to the “Admins” tab. Here you can add colleagues as Admins or Editors (they need to have a user account on VC4A, please ask them to signup if you cannot find them).

People with Admin rights have full access, including to the form builder, where they can change the application form. If you just want them to be able to view applications and help with the pre-screening process, better to add them as Editors.
