Can I ask a monolingual kudoz question?
Yes, but there is not a specific section in the Kudoz area. What you have to do, if you want to ask a question in just one language (p.e.: English to English) is to go to Ask in the Kudoz tab. Then, in the form, click on ‘See more languages’. You will see two lists where you can select the language you want twice. That way, it will be a monolingual question.
