Per T108628, we should advertise the LanguageTool WikiCheck on the Wikipedias for the 20 languages it supports. It is a very useful tool, but probably not well known since it isn't hosted on Tool Labs.
- Create a blurb on meta or mediawiki.org about the LanguageTool WikiCheck (http://community.languagetool.org/wikiCheck/pageCheck/index)
- Set it up for translation using the content translation system (https://www.mediawiki.org/wiki/Help:Extension:Translate/Page_translation_example)
- Send an email to the translate mailing list asking for translations in the 20 languages supported by LanguageTool
- Post the translated notices on the Village Pump/Community Chat pages of the 20 Wikipedias corresponding to those languages (or get a Community Liaison to do it)
