Comment 2 for bug 460980

The project series owner is really the registrant. The project owner is the effective owner regardless of who's name in in the series field. The series owner has no power.

When a user is set as the Release Manager of a series he is given the same access privileges as the project owner. A project driver can creates a series, and he is automatically made the release manager, ensure that the driver has all the power to start, manage, and complete a release.
