Information on what a maintainer is and why they are important to the os db.
Maintainers are privileged users who have the ability to administrate operating systems and versions. Maintainers typically use the operating systems and versions they maintain on a weekely or monthly basis and test them with each new version of QEMU that is released. They also respond to forum posts for their applications/versions and review and process test results and screenshots that users submit. Please see the maintainer's guidelines for more information on the kinds of things a maintainer has stewardship over.
Maintainers are crucial to the usefulness of the OS DB as they ensure that information is kept up-to-date. With the large number of applications and versions present in the OS DB today it would be a difficult task for the small number of OS DB admins to try to perform this task.
See the OS DB FAQ for the difference between a maintainer and a super maintainer.
