You might not be aware of it, but LanguageTool has no maintainer for its English rules. So we’re looking for someone who wants to become maintainer. What does this mean? You don’t have to be a software developer - maintaining a language means writing new rules, and improving the old rules, for example fixing false alarms. The rules and the process of writing new rules is described on our homepage (http://www.languagetool.org/development/) and on the Wiki (http://languagetool.wikidot.com/).
What does this get you? Help improving LanguageTool, probably the most powerful Open Source proofreading tool. LanguageTool 1.5 was downloaded more than 40,000 times, so your work is valued by a lot of people.
How to become maintainer? Just send us some new rules, or improve existing ones. After some good patches, you’ll become maintainer.
