Permissions

Users have different abilities depending on the access level they have in a particular group or project.

If a user is both in a project group and in the project itself, the highest permission level is used.

If a user is a GitLab administrator they receive all permissions.

In order for a group to appear as public and be browsable, it must contain at least one public project.

Any user can remove themselves from a group, unless they are the last Owner of the group.
