What is behind the decision of Russian-speaking parents to send their children to Latvian-medium school? How some public signs in Latvia become a controversial issue? How linguistic landscapes can be used in foreign language pedagogy? What are similarities and differences in language use of two Latvian-Estonian bilinguals? What happens in Estonian-English-Japanese trilingual communication on Facebook? What does a comparison between Tallinn and Vilnius linguistic landscape tells us? Whether and how Lithuanians in the UK and Norway maintain Lithuania? Do siblings from the same Lithuanian family in Australia have a similar command of Lithuanian?
