NewsOffice is a file based news management system. It started as an experiment to support PHP hosting providers that did not offer databases on their platform. This was years and years and years ago, back when I was just getting started with software development.
NewsOffice was made to help people like me create simple blogs and news pages without requiring a database. It features a Rich Text editor, easy news manager, categories and supported file uploads.
The project is available on GitHub for archive purposes. Even though I don't work on it anymore, people who still use it can still access the source code.
The NewsOffice project is no longer supported. It's very, very old. If possible, I suggest switching to a more modern blog system.
