Why is a specific section locked?
If you start using Yamdu, this might happen from time to time. Don’t panic. It all about rights-management. If you feel like you should be able to have access to certain areas of Yamdu, then please notify your administrator. Admins are declared as such in the crew list (“crew”). The admin can decide, whether to allow access or not and/or if you might need an additional position within the project to which those access-rights are already linked.
