The project owner is the person who created the project - project participants are invited. Each user has the right to create his own projects and is therefore the owner of all this data. The project owner has all administrator rights. He is allowed to invite other participants, delete them and change their permissions. He is allowed to edit or update all plans and documents of other roles and can also upload files on behalf of other roles. In contrast to project administrators, the project owner is the only one who can delete his projects. Access to his projects can never be withdrawn from him as owner. Project participants have free access to the project and can upload, download and send plans with their project login. They can only log in with their Planfred access data to projects to which they have been invited. Each participant can only update or edit data from their own role. A participant has read-only rights to plans and documents of other roles. See manual S1 The permission system briefly explained
