I'm here mostly for editing an open Lower Sorbian grammar textbook. Not being a Lower Sorbian speaker, I'll base on existing grammars. It'd be helpful, as no detailed material on this matter is available on the Internet. It'll also help another Wikimedia project, namely Lower Sorbian Wikiepdia, as now it suffers from not enough big number of editors. --MiroSielczanin (discusscontribs) 15:45, 8 December 2013 (UTC)
