Listed below are the languages for those sections of Wikipedia where I made at least a dozen meaningful edits, up to creating new articles.
What levels below 4 mean:
3 - I can communicate, read and write easily;
2 - I can communicate “like a tourist”, but from time to time I “freeze” when I bump into an unfamiliar word or topic; I feel much more comfortable with written texts;
1 - I can read (especially with a dictionary), sometimes even write, but this rarely happens and requires brain efforts.
0 - I had "some experience" (which means I can read letters and know some words and phrases, but nothing more).
Language proficiency changes over time; For example, over the past 5 years, my French skills improved significantly, while Esperanto, on the contrary, is rarely used at all, and I seem to be forgetting it. Belarusian and Bulgarian stand apart - I can easily understand texts and speech of other people - but at the same time I don't speak at all, so they still fall into category 1.
