Hallo Welt! is one of the top addresses for any questions about wikis, blogs and social networks. Years of practical experience in MediaWiki projects is one of Hallo Welt!'s expertise. We support initiators with implentation, wiki gardners with maintenance and users in their daily work. The developers of Hallo Welt! focus technologically on fully developed open-source-solutions.
So we're also the producer of the MediaWiki distribution BlueSpice.
