Contributors are OpenBSD users who have the skills necessary to add features to the operating system, fix problems, or write documentation. Almost anyone can be a contributor. Problems range from a typographical error in the documentation to a device driver that crashes the system under particular circumstances. Every feature that is included in OpenBSD is there because some contributor took the time to sit down and write the code for it. Contributors who submit careful, correct fixes are welcome in the OpenBSD group.
If a contributor submits enough fixes of high enough quality, he may be offered the role of committer.
