Church.net (a.k.a "Црква.нет") is a Serbian Orthodox community that gathers Orthodox Christians from all around the world. It was founded by the orthodox priests at the missionary sector. It is open to everyone, and the goal is to bring people to Orthodox Christianity to see its wisdom and beauty. You can check the project at Church.net. I have contributed on that project by creating "Orthodox Calendar" (which you can see on projects page) and current weather forecast. I have also contributed to its side project called "Поуке.орг" by creating a CSS "Dark Mode" theme for the site's UI.
