I've been speaking Esperanto for a few years, my level is maybe B2. I can give you an introductory course of the language. Online or in Kraków. I am a native speaker of Polish, if you would be interested. I would be interested in lessons in English, simple German (I haven't practiced the language for a long time) or basic lessons in pretty much any other language. I am especially interested in learning from go/weiqi/baduk players. There are many skills I would gladly accept in exchange, so don't hesitate to message me.
