Hi.
We are an enterprise who develops one project and deploys it to a lot of customers. So we have one main project and a lot of subprojects depending of the main one. Everytime we create a subproject, we have to set it up to allow the users of the main project to work in it too.
This is dissapointing, because it means i can't fully create a project with standard permissions.

So, i ask for an option that allow a subproject to inherit the members of its main project.
