Hello, Giraffe 28, that is a very good idea. In the same way, I can recommend Tartu University. In 2013 I spent there two weeks at the Summer language course. It was a great experience: the language lessons of course, but also the program of excursions, cinema and so on. Instead of a hotel I decided to live with a family. You can’t get better contact to the country and it’s culture. This year’s summer course is open for registration until the end of April. Here is the link: https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://ut.ee/en/estonian-language-summer-courses&ved=2ahUKEwizr_bKsamTAxWFhv0HHaDCAY8QFnoECBoQAQ&usg=AOvVaw05z6OeMa6mrHiigUMosrIq
And the teachers were very dedicated. Perhaps they would be interested in helping to develop Estonian on LingQ.
