For English, the rules in some categories such as Plain English and Wikipedia are deactivated by default. Thus, languagetool.org gives no warning for the text “All things considered, you can…”, but on my standalone copy of LT, I get a warning. On https://languagetool.org/, is it possible to active these rules?
If yes, how?
If no, in the Pricing section, I suggest that you add a note to tell people that the stand-alone version can find more errors.
Update: All strings of languagetool.org should now be ready for translation on http://webtranslateit.com. Your changes at webtranslateit.com do not yet automatically show up on the website, I currently need to run a command for that. If you still spot untranslated strings in a few days even though you think you’ve translated everything, please let me know.
