Samotsvety — Website: https://samotsvety.org

Note: The Wikidata source explicitly lists the official website as 'http://www.samotsvety.ru/' while also mentioning 'http://www.samotsvetu.ru' as a separate entry. The claim states the website is 'http://www.samotsvetu.ru', but the source identifies 'http://www.samotsvety.ru/' as the official website. These are different URLs (samotsvety vs samotsvetu), and the source clearly distinguishes them, with the former being marked as the official website.
