The community group I represent is a not-for-profit organization -- either a 501(c)3, an unincorporated club, a park, a library or a school. Its basic orientation is not commercial, though it may sell items such as books, T-shirts and other material related to its work on a small scale. It will sell nothing through the website it creates here on postnet.com. It will include no advertisements for commercial enterprises on this website, although it may refer in ordinary text, containing no commercial messages, to other organizations that sponsor or contribute to it.
