Hi. I understand that this is a very old comment, but I'll try anyways, so if you're not interested, feel free to not accept this message. I saw the list of languages u're interested in and one of them being Czech, my first language. There was also plenty of other languages we share our interest in, so I just thought about contacting you. If you're still interested, I'd be more than happy to get into contact with you.
