Can gitlab project group and user group be separated? Sometimes you don’t want the user to have the relevant project permissions, but you want the user to belong to this group and create their own projects in it, or what better solution is there?
It sounds like you want two seperate groups, one with the permissions you want the user to have and one to own the project.
If you create a new group for the latter, you can move the project in “Settings”/“General”/“Advanced”/“Transfer project” (you might need to be instance adminstrator to have access to that feature).
